  • TRANSMITTER PHOTONIC INTEGRATED CIRCUITS (TxPICs) AND OPTICAL TRANSPORT NETWORK SYSTEM EMPLOYING TxPICs
    Publication number: 20080044128
    Abstract: A photonic integrated circuit (PIC) chip comprising an array of modulated sources, each providing a modulated signal output at a channel wavelength different from the channel wavelength of other modulated sources and a wavelength selective combiner having an input optically coupled to received all the signal outputs from the modulated sources and provide a combined output signal on an output waveguide from the chip. The modulated sources, combiner and output waveguide are all integrated on the same chip.

  • Method of manufacturing and apparatus for a transmitter photonic integrated circuit (TXPIC) chip
    Publication number: 20060228067
    Abstract: A monolithic photonic integrated circuit (PIC) chip where the active waveguide cores of the modulated sources of the PIC are multiple quantum wells (MQWs) and the passive waveguide cores of an optical combiner are a bulk layer or material. The cores of the waveguide cores may be a quaternary such as InGaAsP or InAlGaAs.
