BNC Facility Status 31 Jan 07 4:00 PM
by John Weaver 31 Jan '07

31 Jan '07

The campus steam system is gradually building up pressure. It normally runs at 115 psi, and has now recovered to approximately 75 psi. This is compared to 0 earlier today, when we were in the midst of the problem. This recovery is very good, but we are not back to the situation where we can restart all of our systems. Once restarted, we wish to ensure that everything stabilizes and we don't overtax any of our upcoming systems. For this reason: The cleanroom will be closed until 8:00 AM Thursday, 1 Feb 07. Hazardous chemical processing (i.e., processing in hoods) in the laboratories will be closed until 8:00 AM Thursday, 1 Feb 07, as well. Other laboratory processing, including using squirt-bottles of alcohol, etc., is allowed, effective immediately. Thank you for both your understanding and cooperation during this unexpected campus-wide event. John Weaver John R.

Status of BNC 31 Jan 07 Noon
by Willison, Sheryl L 31 Jan '07

31 Jan '07

As you may have heard, the campus lost power this morning. One aftereffect of the power loss was the loss of campus-wide steam. To keep the cleanroom at a positive pressure and to prevent other building issues, we had to shut down all exhaust systems in the building. Because of these issues: The cleanroom is closed - please do not enter No chemical processing is allowed in the laboratories - even simple solvents Temperatures will be highly unstable. Do not run temperature-sensitive equipment or processes. The best prediction from Purdue Physical Facilities is that the steam should be stabilized in 3-4 hours from now, approximately 4:00 pm. Obviously that is an estimate - I will keep you posted as I learn anything new. Thank you for understanding. John Weaver Facility Manager Birck Nanotechnology Center

SEMINAR ANNOUNCEMENT: THURS. Feb 1; 10:30 AM; BRK 1001 . . . Sangho Kim, "Hexagonal Prism Blue Diode Laser Using Whispering Gallery Mode (WGM) Resonances"
by Starewich, Deborah S. 30 Jan '07

Hexagonal Prism Blue Diode Laser Using Whispering Gallery Mode (WGM) Resonances Thursday, February 1, 2007 Birck Nanotechnology Building, Room 1001 10:30 A.M. Sangho Kim Purdue University Semiconductor lasers have many important applications, including communication technologies, optical storage, printing, and molecular detection. The range of applications could be broadened significantly if the lasers could be made smaller and with lower threshold currents. Todays in-plane semiconductor diode lasers are large discrete devices (about 100 x 400 microns), a form factor that results in part from the performance requirements associated with the optical cavity. To reduce the cavity length, it is necessary to increase the reflectivity of the mirrors for example, by cleaving the crystal and coating the facets with a dielectric multilayer - adding complexity to the fabrication process. Although high-performance vertical cavity lasers can be fabricated from III-V semiconductor heterostructures, the requisite high reflectivities of the mirrors necessitate the fabrication of multilayers with hundreds of periods and thickness control on the order of 1% or better. An alternative design that permits a smaller cavity and active region with a simple fabrication process is the hexagonal prism laser diode. With the hexagonal cavity geometry, whispering gallery mode (WGM) resonances are established by total internal reflection (TIR), which alleviates the need for multilayer reflector coatings as required for small in-plane and vertical cavity lasers. In addition, the high reflection efficiency from TIR enables a lower current density threshold, which is of great utility from a device perspective. The WGM resonance path for two-dimensional hexagonal devices allows reduced device sizes (~2.6x) while maintaining resonance lengths equivalent to one-dimensional in-plane lasers. Hexagonal prism lasers were fabricated by reactive ion etching of (In,Ga)N multi-quantum-well light-emitting diode heterostructures designed to emit in the blue portion of the spectrum, Unlike the optically-pumped microdisk lasers that have been reported recently, the 160 micron diameter hexagonal prism laser is electrically-pumped and demonstrates lasing at 480nm (+/-5nm) with a threshold voltage and current density of 9V and 7kA/cm2, respectively. The performance of these hexagonal prism diode lasers is expected to improve significantly with the further development of a selective growth process to fabricate self-organized hexagonal prism structures. Bio Sangho Kim is a Ph.D. student in the Electrical and Computer Engineering department at Purdue University. He is advised by Prof. Timothy D. Sands and supported in part by the Institute for Nanoelectronics and Computing (INAC). Mr. Kim received his B.E. degree in 1998 from Kwangwoon University, South Korea and a M.S. degree in 2002 from Purdue University. His main research interest is in the field of low threshold UV/blue lasers for optoelectronic integrated circuits and sensors.

Dear BNC faculty or staff member: This is just a friendly reminder that we need the pdf files for your BNC publications by January 30th for posting on the e-Pubs site (see below). Please send your pdf files to Deborah at your earliest convenience. To those who have already completed this task, MANY THANKS!

Each publication is entered in a format that provides maximum access in accordance with the rights of the publisher.

The BNC staff will handle data entry and redundant submissions. Please continue to include the BNC in your author affiliation when appropriate, and ask those who use the facilities for which you are PIC to acknowledge the BNC. We have decided not to include publications that do not mention the BNC to maintain the integrity of the database. Besides promoting your research, the scholarly output included in this database will be used by the BNCs Internal Advisory Committee and the director (me) in our annual evaluations of space utilization in the BNC building. Finally, we plan to ask for these publications each January in concert with similar requests by the schools and departments. If you would like to provide a pdf of each paper as it is published, please do. > > Thanks in advance for your cooperation. I hope you find the e-Pubs site to be a valuable venue for promoting your research and the research of your BNC and Discovery Park colleagues. > > Regards- > > Tim
