摘要： A laser module having a laser optically coupled with an optical fiber via a collimating lens and a focusing lens is formed. The laser is mounted in a laser housing so that its laser light output is directed toward a laser housing wall opening in a laser housing wall of the laser housing. A lens-fiber housing having a lens installed in a first end thereof and a light-receiving input end of the fiber disposed in a bore at a second end thereof is provided. The lens and input end of the fiber form a collimator. The lens-fiber housing is mounted from the outside of the laser housing to the laser housing wall to receive collimated light transmitted from inside the laser housing through the laser housing wall opening. The collimating lens is actively aligned in the laser housing, between the laser and the laser housing wall opening, to determine an aligned position. The collimating lens is secured in the laser housing at the aligned position.

The apparatus has a reflectively coupled zigzag waveguide device for receiving a portion of light output by the tunable laser, the zigzag waveguide device having a plurality of filters, each having a passband centered at a respective one of the plurality of target wavelengths, whereby said zigzag waveguide device produces a plurality of filtered light outputs. A plurality of photosensors is provided, one for each of said plurality of filters, each said filter positioned to receive a respective one of the plurality of filtered light outputs, each said filter producing a filter output signal related to the intensity of said portion of light in the passband of the corresponding filter. A processor generates, in response to the plurality of filter output signals, a control signal to adjust the lasing wavelength of the tunable laser to achieve or maintain said selected one of the target wavelengths. In one embodiment, the zigzag waveguide device includes a first waveguide that is coupled to the laser to receive light output.

摘要： An optical transceiver generally includes an injection locked (IL) laser configured to generate a transmit (Tx) optical signal for transmission over an optical network and a laser driver circuit configured to modulate the IL laser based on a Tx data signal. The Tx data signal may be provided to the optical transceiver for transmission over the optical network. The Tx data signal may include a crossing point level associated with a transition between a first signal level and a second signal level. The optical transceiver may also include a crossing point control circuit configured to apply distortion to the Tx data signal, the distortion to increase the crossing point level.

摘要： A compact multi-channel optical may include a multi-channel transmitter optical subassembly (TOSA), a multi-channel receiver optical subassembly (ROSA) and a circuit board configured and arranged to fit within a relatively small space. The multi-channel ROSA is spaced from the circuit board to allow circuit components to be mounted between the circuit board and the ROSA. The multi-channel ROSA may also be inverted and mounted proximate a transceiver top housing portion, for example, using an L-shaped ROSA support, to transfer heat from the ROSA to the transceiver housing portion. 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).
