Refractive index profile optimization in diffused graded index lenses
(1975-10)
Refractive index profiles resulting from simple diffusion processes in glass are calculated, and optimum choices of diffusion parameters are chosen from minimum error in approximating focusing refractive index profiles. ...
A new waveguide switch/modulator for integrated optics
(1975)
A waveguide optical switch and/or modulator device is described that uses a single-mode waveguide version of the Mach-Zehnder interferometer. A mode selective branching waveguide is used for switching, and modulation can ...
