Abstract: A multi-channel transmitter optical subassembly (TOSA) with an off-center fiber in an optical coupling is disclosed, and can provide passive compensation for beam displacement introduced by optical isolators. The optical coupling receptacle can include an optical isolator configured to receive a focused light beam from a focus lens within the TOSA. The optical coupling receptacle may be offset such that a center line of the focused light beam entering the optical isolator is offset from a center line of a fiber within optical coupling receptacle. Thus the optical isolator receives the focused light beam from the focus lens and introduces beam displacement such that an optical signal is launched generally along a center line of the fiber. Thus the expected beam displacement introduced by the optical isolator is eliminated or otherwise mitigated by the offset between a center line of the fiber and a center position of the focus lens.

Abstract: A multi-channel transmitter optical subassembly (TOSA) including staggered transistor outline (TO) can laser package placement to provide enhanced coupling and optical power is disclosed, and may be used in an optical transceiver for transmitting an optical signal. The TOSA comprises a housing that includes plurality of sidewall openings with each sidewall opening configured to couple to a TO can laser package to provide coarse wavelength division multiplexing. The housing includes at least first and second sidewall openings on a first sidewall, and a third sidewall opening disposed on a sidewall opposing the first sidewall and being positioned at generally a mid-point between the first and second sidewall openings. This staggered and opposing sidewall opening arrangement allows an increased distance between adjacent sidewall openings, and thus, the TOSA may increase optical power and yield by providing additional space for performing post-attachment alignment of TO can laser packages.

A method to etch a scribe line on a semiconductor wafer generally includes: applying a mask layer to a surface of the wafer; photolithographically opening a window in the mask layer along the scribe line; etching a trench in the wafer using a chemical etchant that operates on the wafer through the window opening, wherein the chemical etchant selectively etches through crystal planes of the wafer to generate a V-groove profile associated with the trench; and cleaving the wafer along the etched trench associated with the scribe line through application of a force to one or more regions of the wafer.

Abstract: A multi-channel optical transceiver includes a transmitter optical subassembly (TOSA) with a thermal arrayed waveguide grating (AWG) for multiplexing optical signals and a receiver optical subassembly (ROSA) with an athermal AWG for demultiplexing optical signals. The TOSA may also include a laser array optically coupled to the thermal AWG and a temperature control system thermally coupled to the laser array and the thermal AWG to control temperature for wavelength tuning. The temperature control system in the TOSA may include a thermoelectric cooler (TEC) that cools both the laser array and the thermal AWG. Because the athermal AWG in the ROSA is temperature independent, the ROSA does not include a TEC, thereby reducing power consumption and conserving space. The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

Abstract: A tunable laser with multiple in-line sections generally includes a semiconductor laser body with a plurality of in-line laser sections each configured to be driven independently to generate laser light at a wavelength within a different respective wavelength range. The wavelength of the light generated in each of the laser sections may be tuned, in response to a temperature change, to a channel wavelength within the respective wavelength range. The laser light generated in each selected one of the laser sections is emitted from a front facet of the laser body. By selectively generating light in one or more of the laser sections, one or more channel wavelengths may be selected for lasing and transmission. The tunable laser with multiple in-line sections may be used, for example, in a tunable transmitter in an optical networking unit (ONU) in a WDM passive optical network (PON) to select a transmission channel wavelength.
