An externally modulated transmitter was linearized for AM subcarrier multiplexing (AM-SCM) video transmission. Linearization was accomplished by combining the outputs of two lithium niobate Mach-Zehnder interferometers which were simultaneously modul

We propose arrays of all-passive remote sensors with freedom from both source phase-induced intensity noise and cross talk between sensors. These arrays employ high-duty-cycle time-domain addressing, utilize laser diodes, and have downlead insensitiv

When a single-mode fiber is used at a wavelength below the cutoff wavelength, the fiber guides second-order modes, which travel at different phase velocities from the fundamental mode. Periodically stressing this two-mode fiber once per beat length c

Periodically stressing a birefringent fiber once per beat length can cause coherent coupling to occur between polarization modes. Such a birefringent-fiber polarization coupler is described here. More than 30 dB of power transfer between polarization

A cladding-pumped Nd:silica fiber with a fundamental-mode cut-off near 1000 nm was used to build an amplifier with gain over a range near 920 nm. Pulses from an Nd:YVO4 passively Q-switched laser were amplified and then frequency doubled in LBO to pr

This paper describes a method of multiplexing several optical signals onto a single spatial channel (e.g., a single-mode fiber) using a short coherence length continuous wave light source. Several system configurations which utilize this technique ar

This paper describes and analyzes a particular application of high duty-cycle time-division multiplexing to the separation and identification of signals from an interferometric sensor array. Using the method discussed here, the coherence length of th

This paper is concerned with a new approach to multiplexing several remote sensors using control of optical coherence in place of the usual timedomain or frequency-domain techniques.1 Demonstration of one such system in bulk-optic form has been repor

The paper presents a new class of all-fibre devices based upon periodic coupling principles. The two basic devices which are described are a birefringent fibre polarisation coupler and a two-mode fibre transverse mode coupler. Both devices consist of
