Abstract
A micro-fabrication method of manufacturing optical assemblies and a temperature compensated optical isolator. The manufacturing method employs a lamination procedure to create an array of optics-receiving micro-fixtures. The method is well adapted for the automated manufacturing of optical assemblies. Desirably, the method provides for high speed, high volume production, thereby advantageously, maintaining low manufacturing costs. The isolator utilizes a bimetallic element to rotate a polarization element of the isolator in response to temperature variations. The isolator maintains an effectively constant isolation over a substantially wide temperature range. Advantageously, the isolator is simple, compact and a viable solution to a wide range of optical applications.
