Abstract: A temperature controlled multi-channel transmitter optical subassembly (TOSA) may be used in a multi-channel optical transceiver. The temperature controlled multi-channel TOSA generally includes an array of lasers optically coupled to an optical multiplexer, such as an arrayed waveguide grating (AWG), to combine multiple optical signals at different channel wavelengths. The lasers may be thermally tuned to the channel wavelengths by establishing a global temperature for the array of lasers and separately raising local temperatures of individual lasers in response to monitored wavelengths associated with the lasers. A temperature control device, such as a TEC cooler coupled to the laser array, may provide the global temperature and individual heaters, such as resistors adjacent respective lasers, may provide the local temperatures. 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: An optical component holder having a base portion with a chamfered (or step) portion is disclosed herein that allows a technician to position and partially insert the same within an associated opening using a relatively minor amount of force. The chamfered portion of the base portion operates, in a general sense, as a guide that ensures proper alignment of the optical component holder and allows the same to travel a predetermined distance within the opening before being blocked from further travel by "bottoming" out when the wider portion of the base is at the edge of the associated opening. Thus, the chamfered portion provides an alignment feature to provide tactile feedback that indicates to the technician that the optical component holder is aligned and evenly inserted into an associated opening prior to supplying additional force to press the optical component holder fully into a housing.

Abstract: Techniques are disclosed for filling gaps formed between a press-fit component and an optical subassembly housing to introduce a seal or barrier that can prevent or otherwise mitigate the ingress of contaminants. In an embodiment, a layer of sealant material is applied to one or more surfaces of an optical component prior to press-fitting the component into an optical subassembly housing. Alternatively, or in addition to applying sealant to one or more surfaces of an optical component, a layer of sealant material may be disposed on an interface formed between an outer surface of the optical subassembly housing and the optical component press-fit into the same. Techniques disclosed herein are particularly well suited for small form-factor optical subassemblies that include one or more optical components press-fit into openings of a subassembly housing during manufacturing.

Abstract: A coaxial transmitter optical subassembly (TOSA) including a cuboid type TO laser package may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. The cuboid type TO laser package is made of a thermally conductive material and has substantially flat outer surfaces that may be thermally coupled to substantially flat outer surfaces on a transceiver housing and/or on other cuboid type TO laser packages. An optical transceiver may include multiple coaxial TOSAs with the cuboid type TO laser packages stacked in the transceiver housing. The cuboid type TO laser package may thus provide improved thermal characteristics and a reduced size within the optical transceiver.
