LOW-LOSS COMPACT REFLECTIVE TURNS IN OPTICAL WAVEGUIDES.

摘要

This invention pertains to a device (10) and method for making same. The device (10) includes a substrate (12) suitable for supporting pathways for optical signals; separate pathways disposed on the substrate (12) suitable for propagating optical signals, the pathways including an input and an output optical pathway; and a reflective surface in operative contact with the input and output pathways for receiving an optical signal from the input pathway and reflecting the optical signal into the output pathway. The method for making the device (10) includes the steps of providing two separate optical pathways on a single substrate (12), one being an input pathway and the other being an output pathway.
