Abstract: A multi-wavelength laser array (10) of a plurality of emitters in a diode bar (12) or stack where each beam passes through a first deflector (12) comprising an array of prisms and is deflected by a different angle to be incident upon a uniform volume holographic grating (18). A portion of the beam is diffracted by the grating (18) and reflected by a second deflector (20) as a feedback portion while a further portion provides a wavelength tuned output unique to each emitter. The arrangement of a uniform volume holographic grating with deflectors such as phaseplates eliminates the need to use expensive wavelength chirped gratings.

Abstract: A laser array mux assembly generally includes an array of laser emitters coupled to an optical multiplexer, such as an arrayed waveguide grating (AWG), with an external partial reflector after the multiplexer. Each of the laser emitters may include a gain region that emits light across a range of wavelengths including, for example, channel wavelengths in an optical communication system. The AWG filters the emitted light from each of the laser emitters at different channel wavelengths associated with each of the laser emitters. The reflector reflects at least a portion of the filtered light such that lasing occurs at the channel wavelengths of the reflected light. The laser array mux assembly may be used to generate an optical signal at a selected channel wavelength or to generate and combine optical signals at multiple channel wavelengths.

Abstract: The present document relates to the field of optical access networks. In particular, the present document relates to an optical transmitter, in particular (but not exclusively) for a WDM (Wavelength Division Multiplexing) passive optical network, and to a WDM PON comprising such an optical transmitter. An optical transmitter arrangement (7) is described. The arrangement (7) comprises a first mirror (41) and a second mirror (64) at a first end and a second end of a cavity, respectively; an optical amplifier (63) configured to amplify light polarized in a first polarization plane; wherein the optical amplifier (63) is positioned within the cavity upstream the first mirror (64); an optical waveguide (5-2) configured to transmit light from the optical amplifier (63) to the second mirror (41) and vice versa; a first non-reciprocal polarization rotator (82) positioned within the cavity upstream of the optical amplifier (63) and downstream of the optical waveguide (5-2); and a second non-reciprocal polarization rotator (81) positioned within the cavity upstream of the optical waveguide (5-2) and downstream of the first mirror (41); wherein the first (82) and second (81) non-reciprocal polarization rotators are configured to rotate the polarization of the light such that light which re-enters the optical amplifier (63) after having been reflected by the second mirror (41) is polarized in the first polarization plane.
