A bonding fixture. In some embodiments, the fixture includes: a plate for supporting a central region of the wafer, the central region including 80% of the area of the wafer; and a frame for supporting: the edge of the wafer, and the edge of the plate, the frame having: a first vacuum passage, for pulling the wafer against an upper surface of the frame, and a second vacuum passage, for pulling the plate against the frame.

Bonding fixture

An optical multiplexer and methods of making and calibrating the same are disclosed. A method of aligning components in a multichannel optical/optoelectronic transmitter includes passively fixing a plurality of light emitters in place on a substrate; adjusting positions of a first lens passing light from a first light emitter and an optical signal transmission medium receiving the light from the first light emitter until a far field spot of the light from the first light emitter is at or near an end of the transmission medium; fixing one or more optical subassemblies on the substrate; and adjusting positions of the optical subassembly(ies) to align light from the remaining light emitters with the far field spot. Some embodiments include multiple optical subassemblies, each including a lens and a filter. Other embodiments include one optical subassembly including a mirror and a beam combiner.

Multichannel optical transmitter and method of aligning components in the same

Methods for manufacturing and using an optical or optoelectronic device are disclosed. The optical or optoelectronic device and related methods may be useful as an optical or optoelectronic transceiver or for the processing of optical signals. The optical or optoelectronic device generally comprises a light-transmitting medium configured to transmit a first light beam; a light-receiving unit configured to receive and process a focused, reflected light beam; a first mirror or beam splitter configured to reflect at least a first portion of the transmitted light beam away from the light-receiving unit; a lens configured to focus the reflected light beam; and a second mirror configured to reflect the focused, reflected light beam towards the light-receiving unit.

Optical received with reduced cavity size and methods of making and using the same

Optical receiver with reduced cavity size and methods of making and using the same

Methods and apparatuses for reducing the sensitivity of an optical signal to polarization. The method generally includes (i) reflecting the optical signal from a first mirror at a first angle relative to the optical signal to a second mirror at a second angle, and (ii) further reflecting the reflected optical signal from the second mirror to a receiver. The apparatus generally comprises (i) a first mirror at a first angle relative to an incident optical signal and configured to reflect the incident optical signal, (ii) a second mirror at a second angle configured to further reflect the reflected optical signal to a first receiver, and (iii) a lens configured to focus and/or collimate the optical signal or the reflected optical signal. The first angle is configured to reduce polarization of the reflected optical signal, thereby maximizing the intensity or power of the optical signal.
