    Abstract: 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.

    Abstract: The present disclosure provides a transmission system, apparatus and method to provide for variable channel spacing in multiplexed or combined optical signals for transmission over a network infrastructure. The channel spacing may be monitored and maintained at desired values in order to maximize the channel density under various conditions related to the network infrastructure. The individual carrier frequencies associated with each signal channel of the transmission system may be individually controlled to define the desired channel. The channel spacing may be altered to provide for higher channel densities increasing system capacity, or to provide for lower channel densities improving the overall reach of the transmission system. The channel spacing may be continuously monitored and maintained at desired values allowing for rapid and automated reconfiguration of the transmission system, which may result in maximized capacity and reduced costs.

    Abstract: 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.
