ALL-USER MEETING
Did you miss the All-User Meeting?
You have until Friday March 31st to go through the slideshow with your professor and hand in the signed paper work to BRK 1220.  http://www.purdue.edu/discoverypark/birck/operations/safety.php has the slideshow and paperwork you need to fill out.

Cleanroom Printer

A user brought to our attention an issue with the gowning room printer.  It frequently jams when cleanroom paper is fed through.  Birck uses a couple of different cleanroom papers, so Lorraine is going to consult with local printer suppliers, and actually take samples of our papers to them, in order to find a suitable printer for our needs.

Headphones in the Cleanroom

Though we don't have an official policy against the use of headphones in the cleanroom. We would strongly discourage there use. The staff has observed situations on a number of occasions where individuals have almost run into each other because one of the two were listening to headphones. With the use of chemicals and delicate samples being processed it only stands to reason that this distraction could have a negative impact on the operations of the cleanroom, especially form a safety standpoint.

NANODAYS

Dear Birck faculty and students,

We are planning our yearly NanoDays outreach event, for April 6th and 7th from 9am - 2pm and Girl Scout/Birck Family Evening for April 5th 6-8pm.    As in years past, we would really appreciate having some research groups provide demonstration/activity tables alongside our standing lineup of activities. They are generally aimed at kids in elementary school up to high school.

Please contact me ndilley at purdue.edu<mailto:ndilley at purdue.edu>  by February 24th, 2017 if you would like your group to have an activity table at this year's Nanodays.

Thank you very much for your interest in engaging kids in science!

Best regards,
Neil

Purdue's Birck Nanotechnology Center has an exciting volunteer opportunity for students in the technical, education, and management fields. Participants will have the opportunity to:

*         Gain professional experience explaining scientific concepts to people from non-technical backgrounds.

*         Support the future of STEM programs by introducing grade schoolers and high school students to the miniscule world of atoms, molecules, and nanoscale forces.

*         Participate with other students/researchers in a nationwide festival celebrating nanotechnology science and education.

Since 2010, the Birck Nanotechnology Center at Discovery Park has participated in NISE NanoDays, a program that promotes science and technology education nationwide. Volunteers will staff activity stations and assist visitors as they investigate different scientific concepts. Some example activities for 2017 include static electricity, DNA, and ultraviolet light. No prior knowledge is required to volunteer, just an enthusiasm for science and science education.

Local vendors will be providing food for volunteer training and all three days of the event.

Volunteers can attend any or all of the following shifts:
Wednesday:      4/5/17, 5:30 PM - 8:00 PM

Thursday:            4/6/17, 8:45 AM - 11:30 AM
                                4/6/17, 11:15 AM - 2:00 PM

Friday:                  4/7/17, 8:45 AM - 11:30 AM
4/7/17, 11:15 AM - 2:00 PM

Training is mandatory and will be provided in the Birck atrium. The schedule is:
Tuesday:              3/28/17, 5:00 PM - 6:00 PM (Pizza Party)
  6:00 PM - 7:30 PM (Training Sessions)

Physical Vapor Deposition Run Durations

We received an input this week about pumping speeds of our various PVD systems (evaporators and sputtering systems).  We are evaluating these to see if it makes sense to adjust the standard run times per equipment.

SEMINAR

Flat Photonics Using High Contrast Metastructures

Connie J. Chang-Hasnain
Electrical Engineering and Computer Science University of California, Berkeley, CA
Monday, Feb 13 from 10:30 AM - 11:30 AM Birck 1001

A new class of planar optics has emerged using near-wavelength structures with a large refractive index contrast with its surroundings, known as high contrast metastructures (HCM). Many extraordinary properties can be designed top-down based for integrated optics on a silicon substrate. Using a 1D HCM (known as high contrast gratings) as a high reflectivity mirror, we demonstrated wavelength- sweptable vertical cavity surface emitting lasers (VCSELs) with 10 MHz tuning speed and continuous tuning range. Such wavelength-swept lasers have applications for data communications, LIDAR and optical coherent tomography applications. A single layer HCG can also be designed as high quality-factor surface-normal resonators. I will review recent results using and its applications as biosensor, 4-wave generation, and spatial light modulator. Finally, we also demonstrated a novel design that mimics the color tuning effect of chameleon skin with color change achieved simultaneously in a multiple-color pattern flat structure. In this talk, I will review the physics, experimental demonstrations and novel applications.
