    摘要: 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.

    摘要: 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.

    摘要: Consistent with the present disclosure, an apparatus for producing a control signal for a laser source is provided, comprising an etalon configured to receive light from the laser source and control circuitry that provides the control signal, wherein the control signal is indicative of a comparison of (a) a difference between a forward transmission signal of the etalon and a backward reflection signal of the etalon and (b) the light received by the etalon from the laser source. Alternatively, the control signal is indicative of a comparison of (a) a difference between a forward transmission signal of the etalon and a backward reflection signal of the etalon and (b) a combination of the forward transmission signal of the etalon and the backward reflection signal of the etalon. Also consistent with the present disclosure, a method of aligning an etalon-based wavelength locking apparatus is provided, wherein the etalon of the apparatus is aligned with an optical axis along a direction of propagation of the output of the laser source by monitoring the signals indicative of the forward transmission signal and the backward reflection signal of the etalon.

    摘要: Disclosed is an optical package which is economical to manufacture. An optical component, such as a PIN photodiode, is bonded to a substrate such as silicon with no metallization on its side surfaces. The resulting assembly is solder bonded to the bottom surface of the package so that a side surface of the substrate is adjacent to the bottom surface with essentially no solder therebetween.
