CMOS-compatible optical bench
 A method of aligning, placing, and attaching an optical fiber directly to an electronic, complementary, metal-oxide-semiconductor (CMOS) chip that uses alignment features defined during the CMOS fabrication. The method involves the steps of: i) defining, during the fabrication of an electronic CMOS device, one or more shallow grooves upon the device substrate; ii) disposing an optical fiber within the defined groove(s); and iii) securing the optical fiber within the groove(s). Advantageously, the method may be practiced using a variety of fabrication techniques and apparatus that are compatible with conventional CMOS devices.
