METHOD OF MANUFACTURING OPTICAL DEVICES AND RELATED IMPROVEMENTS

摘要

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 i s a structural defect comprising a plurality of adjacent "point" defects.
