A planar optical modulator operating near 360 nm suitable for ultraviolet spatial light modulation has been constructed. The modulator operates in transmission mode with a 18% change in transmission at 305 V. The modulator is based on using the electric field to shift and broaden the room-temperature resonance of the gallium nitride exciton with electric fields. © 2003 American Institute of Physics.

    Based on the effective mass approximation, the combined effects of the laser field and electric field on exciton states and optical properties in the zinc-blende GaN/AlGaN quantum well (QW) are investigated by means of a variational method. Numerical results show that when the applied electric...

    The Γ[sub 5] and Γ[sub 6] free excitons have been identified in GaN from emission measurements. Another emission peak is also observed which we believe to be the longitudinal free exciton. These measurements along with electrical measurements, which show the sample to have very high peak...

    Electric fields in the GaN underlying the 2DEG of three GaN/AlGaN field effect transistor (FET) structures measured by photoreflectance (PR) using sub-gap excitation were found to be about 210–260kVcm-1, indicating the presence of traps. The sample having the lowest electric field was...

    Photoreflectance has been applied to study the exciton energies and linewidths for hetero- and homoepitaxial GaN layers (i.e., GaN layers grown on sapphire and truly bulk GaN crystal obtained by ammonothermal method). In order to modulate the built-in electric field inside the samples and...
