A method to fabricate chromium‐doped lithium niobate substrates in which the active ions are introduced by thermal diffusion from a film is reported. Chromium concentration depth profiles have been obtained by secondary‐ion‐mass spectrometry an

Rapid Prototyping Technology-Principles and Functional Requirements
In recent years, there has been an intensive search of cost efficient techniques applied to integrated optic device fabrication. One approach with recognized potential is based on laser patterning upon photosensitive materials, which permits the fabr

A detailed comparison between a low-finesse Fabry-Perot cavity and a typical two-beam interferometer is developed and checked experimentally. The consequences of approximating the true Fabry-Perot function by the two-beam function are evaluated for c

A scheme to frequency multiplex a group of sensors based on all-fiber Michelson interferometers is presented. Lead insensibility is obtained by using the two fiber leads of the configuration as an extra Michelson interferometer whose differential pha

We report electroabsorption modulation of light at around 1550 nm in a unipolar InGaAlAs optical waveguide containing an InGaAs/AlAs double-barrier resonant tunneling diode (RTD). The RTD peak-to-valley transition increases the electric field across
