The NanoLab Optical Lab is equipped with various light and laser sources, monochromators, detectors, microscopes, cryogenic systems, and power meters for conducting transmission, absorption, reflection, photoluminescence, electrical luminescence at spectrum from ultraviolet to infrared wavelengths. Equipment is arranged into three groups: Alpha (click here), Delta (click here) and Gamma (click here) stations. The Alpha station is configured to perform UV to Visible PL/EL measurement, whereas the Beta station is for the visible to infrared range. Lasers being employed are 325 nm Liconix HeCd laser, 337 nm PTI Nitrogen pulse laser, 488 Omnichrome Argon laser, 835-870 nm ILX tunable diode laser, and 1002-1028 nm ILX tunable diode laser.  The ILX lasers are pictured to the right in an application for the optical memory project.  Other light sources such as 365 nm Nikon Hg lamp, Oriel quartz halogen lamp and 366 nm UV blak-ray lamp are also being utilized. The Alpha station includes 0.5 m ARC monochromater fitted with photomultiplier or InGaAs semiconductor detector while the Beta station is equipped with 0.27m ISA spectrometer retrofitted with Si-CCD and North Coast liquid cooled hyper-pure Germanium semiconductor detector.  To the left the Beta station is pictured with a portion of the Alpha station in the back right.  Furthermore, transmission, absorption, reflection measurements are measured with Perkin-Elmer UV/VIS/NIR spectrometer. For low temperature research, MMR cryogenic system at around 80 Kevin is also available. There are 4 Nikon microscopes ready in the lab. Two of then have been modified to be either more efficient at UV-Vis transmission or Vis-IR transmission. One has been redesigned for two-step-two-frequency excitation by collinearing two laser sources.  Other facets of optical research are being pursued in parallel with PL/EL measurement. One of the researches currently is focusing on developing novel optical memory device.
