We report on the first demonstration of an electrically-pumped blue VCSEL. Laser action was achieved at a wavelength of 484 nm under pulsed current injection at 77 K. The VCSEL structure was composed of a CdZnSe/ZnSe multi-quantum-well active layer, ZnSe cladding layers, and SiO/sub 2//TiO/sub 2/ distributed Bragg reflectors (DBRs). The CdZnSe/ZnSe epitaxial layers were grown by molecular beam epitaxy (MBE) directly on a GaAs (100) substrate at a growth temperature of 270/spl deg/C. The MQW structure consisted of Cd/sub 0.2/Zn/sub 0.8/Se quantum wells and ZnSe barriers.

In AMLCD (Active Matrix Liquid Crystal display) applications minimizing Cgs, the parasitic capacitance between gate and source of a-Si TFT, reduces flicker, image retention and gray scale nonuniformity and makes it possible to further increase display size and resolution. Cgs is generally minimized by shrinking the device size, e.g. by using ion doping for the n/sup +/ contact formation in a self-aligned trilayer type TFT. We present a TFT with a novel geometry to reduce Cgs and photosensitivity.
