Compact lasers with extended tunability

Abstract: Consistent with the present disclosure, a compact laser with extended tunability (CLET) is provided that includes multiple segments or sections, at least one of which is curved, bent or non-collinear with other segments, so that the CLET has a compact form factor either as a singular laser or when integrated with other devices. The term CLET, as used herein, refers to any of the laser configurations disclosed herein having mirrors and a bent, angled or curved part, portion or section between such mirrors. If bent, the bent portion is preferably oriented at an angle of at least 30 degrees relative to other portions of the CLET. Alternatively, the curve or bend portion may be distributed over different sections of the CLET over a series of arcs, for example. The waveguide extending between the mirrors is continuous, such that light propagating along the waveguide is not divided or split. The waveguide also constitutes a continuous waveguide path.

Reconfigurable time-domain de-multiplexing of optical signals at 40 Gb/s

Abstract: We experimentally demonstrate reconfigurable switching of four 10-Gb/s tributary channels of 40-Gb/s data using a programmable planar lightwave circuit and nonlinear wavelength conversion. Our device is a silica-on-silicon based 6-stage lattice-form Mach-Zehnder interferometer.

Advanced Photonic Integration and the Revolution in Optical Networks

Abstract: Advanced Photonic Integrated Circuits (PICs) have changed the way capacity is added to optical networks. This paper outlines the operational challenges of scaling WDM optical networks to support Internet growth rates using traditional approaches. It describes the advantages PIC-based solutions offer in terms of size, simplicity, power consumption, and reliability. Future directions enabled by advanced photonic integration are considered.

Simultaneous all-optical phase noise mitigation and automatically locked homodyne reception of an incoming QPSK data signal.

Abstract: Simultaneous phase noise mitigation and automatic phase/frequency-locked homodyne reception is demonstrated for a 20-32 Gbaud QPSK signal. A phase quantization function is realized to squeeze the phase noise of the signal by optical wave mixing of the signal, its third-order harmonic, and their corresponding delayed variant conjugates, converting the noisy input into a noise-mitigated signal. In a simultaneous nonlinear process, the noise-mitigated signal is automatically phase- and frequency-locked with a "local" pump laser, avoiding the need for feedback or phase/frequency tracking for homodyne detection. Open eye-diagrams are obtained for in-phase and quadrature-phase components of the signal and ∼2 dB OSNR gain is achieved at BER 10-3.
