Large-scale photonic integrated circuits

We present an overview of Infineras current generation of 100 Gb/s transmitter and receiver PICs as well as results from the next-generation 500 Gb/s PM-QPSK PICs.

Current Status of Large-Scale InP Photonic Integrated Circuits

In this paper, the current state of the art for large-scale InP photonic integrated circuits (PICs) is reviewed with a focus on the devices and technologies that are driving the commercial scaling of highly integrated devices. Specifically, the performance, reliability, and manufacturability of commercial 100-Gb/s dense wavelength-division-multiplexed transmitter and receiver PICs are reviewed as well as next- and future-generation devices (500 Gb/s and beyond). The large-scale PIC enables significant reductions in cost, packaging complexity, size, fiber coupling, and power consumption which have enabled benefits at the component and system level.

The Realization of Large-Scale Photonic Integrated Circuits and the Associated Impact on Fiber-Optic Communication Systems

Large-scale photonic integrated circuits (LS PICs) have been extensively deployed throughout the fiber optic communication network. This paper discusses the properties of the LS PICs, the interaction between them, and what is necessary to create an optical transport system that fully utilizes the properties of the LS PIC

Large-Scale InP Transmitter PICs for PM-DQPSK Fiber Transmission Systems

We report here the first demonstration of a large-scale monolithically integrated InP-based 10-channel 45.6-Gb/s per channel transmitter photonic integrated circuit employing polarization-multiplexed differential quadrature phase-shift keying modulation format.

A 10-wavelength, polarization-multiplexed, monolithically integrated InP transmitter PIC is demonstrated for the first time to operate at 112 Gb/s per wavelength with a coherent receiver PIC.

Measurement and modeling of the angular dispersion in liquid crystal broadband beam steering devices

Liquid crystal beam steering devices behave like blazed diffraction gratings: the design wavelength can be nicely diffracted into a single order. Unfortunately, the grating nature of these devices causes strong angular dispersion of the transmitted light when the incident beam contains a broad spectrum of wavelengths. We characterized the behavior of a liquid crystal beam steerer for broadband illumination. We report experimental measurements of the impulse response of the beam steering device as a function of illumination wavelength. We also compare our results to a theoretical analysis utilizing the beam-propagation method (BPM). We find that even a simple model of the phase profile gives good agreement with the experimental measurements.

Field demonstration of distributed Raman amplification with 3.8-dB Q-improvement for 5 x 120-km transmission

The benefits of distributed Raman amplification are demonstrated in a buried cabled field fiber. The performance improvement of 3.8 dB was achieved in a 5/spl times/120-km 10-Gb/s transmission experiment using 650-mW Raman amplification in each span without apparent damage to the fiber plant. The field results are compared to a similar laboratory experiment using a fusion-spliced fiber to evaluate the effect of finite optical reflections from nonfusion splices in the field fiber.

Large-scale DWDM photonic integrated circuits: a manufacturable and scalable integration platform

Commercial scaling of electronic integrated circuits has proceeded at a fast pace once the initial hurdle to integration was overcome. Recently, it has been shown that record active and passive optical device counts, exceeding 50 discrete components, can be incorporated onto a single monolithic 100 Gbps DWDM transmitter PIC InP chip. We will investigate key production metrics for this large-scale PIC commercial device as well as other analogs to other III-V semiconductor commercial devices. Using the yield management tools pioneered by silicon based electronics, we will present data supporting their scalability and the manufacturability of these large-scale PICs
