Waveguide electro-optic modulation in II-VI compounds
(1973)
Electro-optic intensity modulation is demonstrated in three-dimensional (channel) waveguides fabricated by diffusion techniques in ZnSe and CdS. Typical diffused guide dimensions are 1.6 μm × 19 μm × 2 mm. Two electrode ...
Photoluminescence determinations of Cd diffusion in ZnSe
(1973)
The diffusion constant D(T) of cadmium into single-crystal zinc selenide was measured using a photoluminescence/etch technique. Diffusions were performed in sealed ampoules using cadmium metal and cadmium selenide powder ...
Optical waveguides by diffusion in II-VI compounds
(1972)
Planar optical waveguides have been made by sealed ampoule diffusion of Cd and Se into ZnS and Cd into ZnSe. Three-dimensional diffused guides of Cd-diffused ZnSe have been made by using a masking layer of evaporated ...
Fabrication of single-crystal semiconductor optical waveguides by solid-state diffusion
(1972)
Optical surface waveguides have been fabricated by diffusing selenium into single-crystal CdS substrates to produce graded-composition CdS Se crystals. Planar guides which confine a beam in one dimension and guides produced ...
Fluorescence of graded-band-gap CdSxSe1-x crystals produced by diffusion
(1972)
The fluorescence of CdSxSe1-x mixed crystals with band-gap gradients as large as 1200 eV/cm has been investigated at 77°K. The graded samples were produced by heating CdSe or CdSxSe1-x platelets in a sulfur-selenium ...
