An uncooled, through-hole configured laser module adapted to receive and transmit RF signals to a laser at bandwidths from direct current (DC) to about ten gigahertz. The laser module incorporates an option for two pin-out configurations. One pin-out configuration has one ground pin and one signal pin for operation at about one gigabit/second or one gigahertz. The second high performance pin-out uses two ground pins and one signal pin for operation up to about ten gigabit/second or ten gigahertz.

An optical receiver includes a first substrate including a demultiplexer and a first optical waveguide array. An input of the demultiplexer is configured to receive a wavelength division multiplexed optical input signal having a plurality of channels. Each of the plurality of channels corresponds to one of a plurality of wavelengths. Each of the plurality of outputs is configured to supply a corresponding one of the plurality of channels. The first optical waveguide array has a plurality of inputs. Each of the inputs of the first optical waveguide array is configured to receive a corresponding one of the plurality of channels. A second substrate is in signal communication with the first substrate and includes an optical detector array. The optical detector array has a plurality of inputs, each of which is configured to receive a corresponding one of the plurality of channels and generate an electrical signal in response thereto.

Consistent with one example of the disclosed implementations, a photonic integrated circuit (PIC) may be provided that includes s group of lasers and an arrayed waveguide grating (AWG) disposed on a substrate. Each laser in the group may supply an optical signal, such that each optical signal has a different wavelength. Each laser may be tunable to at least two designated wavelengths, which are separated from one another by a free spectral range (FSR) of the AWG. As a result, the optical signals provided from each laser may be combined by the AWG, regardless of which designated wavelength the optical signals have. Accordingly, a PIC may be provided that has a relatively simple construction but can supply optical signals having tunable wavelengths.

Pairs of distributed feedback (DFB) lasers are provided on a substrate. An arrayed waveguide grating (AWG) is also provided on the substrate having input waveguides, each of which being connected to a corresponding pair of DFB lasers. The wavelengths of optical signals supplied from each pair of DFB lasers may be spectrally spaced from one another by a free spectral range (FSR) of the AWG. By selecting either a first or second DFB laser in a pair and temperature tuning to adjust the wavelength, each pair of DFB lasers can supply optical signals at one of four wavelengths, pairs of which are spectrally spaced from one another by the FSR of the AWG. A widely tunable transmitter may thus be obtained.

An optical transceiver assembly for use in a bidirectional system includes a beam splitter to direct an incoming signal to a photodiode. An outgoing signal from a laser diode is partially transmitted and partially reflected by the splitter. The reflected signal, which may reach the photodiode, constitutes crosstalk which is reduced by orienting the polarization direction of the splitter essentially parallel to that of the outgoing signal from the laser diode. In another embodiment, which enhances coupling efficiency, a single element asphere lens is positioned between the laser diode and the splitter.

An optical transceiver assembly for use in a bidirectional system includes a beam splitter to direct an incoming signal to a photodiode. An outgoing signal from a laser diode is partially transmitted and partially reflected by the splitter. The reflected signal, which may reach the photodiode, constitutes crosstalk which is reduced by means of a cavity positioned to receive the reflected signal and an oblique surface within the cavity adapted to prevent much of the reflected signal from reaching the photodiode.
