Method of manufacturing optical devices and related improvements

Abstract

There is disclosed an improved method of manufacturing of an optical device (40), particularly semiconductor optoelectronic devices such as laser diodes, optical modulators, optical amplifiers, optical switches, and optical detectors. The invention provides a method of manufacturing optical device (40), a device body portion (15) from which the device (40) is to be made including a Quantum Well (QW) structure (30), the method including the step of: processing the device body portion (15) so as to create extended defects at least in a portion (53) of the device portion (5). Each extended defect is a structural defect comprising a plurality of adjacent “point” defects.
