abstract: Indium phosphide (InP) is the most developed platform for photonic integrated circuits (PICs) Of interest is the advancement of this platform for applications that demand high performance, especially high output power, including free space communications and microwave photonics. In this paper, we summarize development of InP based PIC transmitters. Two transmitter types were fabricated: one based on an offset quantum wells (OQW) platform and the other on a quantum well intermixing (QWI) platform. The OQW based transmitter consists of a widely tunable laser, a high speed semiconductor optical amplifier (SOA) a Mach Zehnder modulator, and an output SOA. This transmitter demonstrates a 44 nm tuning range, >45 dB side mode suppression ratio, 14.5 dBm off chip power, and a data rate of 7 Gbps. The second transmitter, based on QWI, utilizes an alternate epitaxial structure to achieve a lower confinement factor for higher SOA output saturation power. This QWI transmitter consists of a distributed Bragg reflector laser, a high speed SOA, an electroabsorption modulator, and an output SOA. The measured off chip power is 19.5 dBm, and a data rate of 20 Gbps is demonstrated. Based on the improved performance with the new epitaxial structure, a novel platform for high power PIC transmitters integrated with low confinement and high power SOAs is described.

abstract: An indium phosphide (InP) based photonic integrated circuit (PIC) transmitter for free space optical communications was demonstrated. The transmitter consists of a sampled grating distributed Bragg reflector (SGDBR) laser, a high speed semiconductor optical amplifier (SOA) a Mach Zehnder modulator, and a high power output booster SOA. The SGDBR laser tunes from 1521 to 1565 nm with >45 dB side mode suppression ratio. The InP PIC was also incorporated into a free space optical link to demonstrate the potential for low cost, size, weight, and power. Error free operation was achieved at 3 Gb/s for an equivalent link length of 180 m (up to 300 m with forward error correction)

abstract: We demonstrate photonic circuits monolithically integrated on an InP based platform for use in coherent communication links. We describe a technology platform that allows for the integration of numerous circuit elements. We show examples of an integrated transmitter which offers an on chip wavelength division multiplexing source with a flat gain profile across a 2 THz band and a new device design to provide a flatted gain over a 5 THz band. We show coherent receivers incorporating an integrated widely tunable local oscillator as well as an optical PLL. Finally, we demonstrate a tunable optical bandpass filter for use in analog coherent radio frequency links with a measured spurious free dynamic range of 86.3 dB Hz2/3 as well as an improved design to exceed 117 dB Hz2/3.

abstract: High power photonic integrated circuits (PICs) are of interest for a variety of applications including microwave photonics, free space optical communications and coherent LiDAR systems [1] [2] Indium phosphide (InP) is the most advanced platform for high performance PICs. InP PICs are particularly attractive for free space optical communications, which requires low cost, size, weight and power (CSWaP) [3] [5] In conventional InP PICs, saturation power of semiconductor optical amplifiers (SOAs) is limited by small modal size and high confinement factor 5\ To improve the SOA saturation power, one approach is to increase the modal size with a flared waveguide, but the large beam dimension in the horizontal direction imposes challenges on the coupling to singlemode fiber [6] A second approach is to reduce the confinement factor. Slab coupled optical waveguides (SCOW) with small confinement factor have been investigated for high power SOAs and lasers. However, it is very challenging to monolithically integrate the SCOW SOAs with other optical elements required for a PIC such as a seed laser and modulator [7] In this work, we have proposed a novel platform enabling the monolithic integration of low confinement SOAs with other high confinement components including a distributed Bragg reflector (DBR) laser and high speed electro absorption modulator (EAM)

abstract: In the recent years, relentless push for higher transmission capacity with lower cost, size, and power dissipation necessitated adoption of photonic integration in all optical communication link hardware. InP photonic technology enables monolithic integration of wide range of photonic functions delivering high performance photonic integrated circuits (PICs) In this article we will review available InP integration technologies and discussed how optical link performance requirements drive the selection of PIC functional sections and integration approaches. We will also present design, integration technology, and performance for several InP PICs that have been commercialized in Datacom, Metro, and Long haul transmission systems.

abstract: Photonic integration in a micrometer thick indium phosphide (InP) membrane on silicon (IMOS) offers intrinsic and high performance optoelectronic functions together with high index contrast nanophotonic circuitries. Recently demonstrated devices have shown competitive performances, including high side mode suppression ratio (SMSR) lasers, ultrafast photodiodes, and significant improvement in critical dimensions. Applications of the IMOS devices and circuits in optical wireless, quantum photonics, and optical cross connects have proven their performances and high potential.
