“…Wavelength tuning can be achieved via the thermo-optic effect, i.e., by heating of the MRRs, which increases the effective waveguide index and thereby the optical length of the MRRs. Further details about MRR Vernier filters can be found in [19][20][21].…”

Abstract:We present a detailed analysis of a semiconductor hybrid laser exploiting spectral control from an external photonic waveguide circuit that provides frequency-selective feedback. Based on a spatially resolved transmission line model (TLM), we have investigated the output power, emission frequency, and the laser spectral linewidth. We find that, if the feedback becomes weaker, the spectral linewidth is larger than predicted by previous models that are based on a modified mean-field approximation, even if these take a strong spatial variation of the gain into account. The observed excess linewidth is caused by additional index fluctuations that are associated with strong spatial gain variations.

“…A coherent transceiver for Ethernet would most likely have to use an integrated semiconductor tunable laser rather than a relatively bulky external cavity laser (ECL). Because of this, there has been great progress in recent years toward compact integrated devices with narrow linewidths [33], [34]. However, the distinctive FM noise spectrum of an integrated SCL can cause standard carrier phase recovery algorithms to fail, even when the 3 dB linewidth of the laser is theoretically narrow enough to allow penalty-free transmission [14].…”

Abstract-We formulate a semiconductor laser rate equationbased approach to carrier recovery in a Bayesian filtering framework. Filter stability and the effect of model inaccuracies (unknown or un-useable rate equation coefficients) are discussed. Two potential application areas are explored: laser characterization and carrier recovery in coherent communication. Two rate equation based Bayesian filters, the particle filter and extended Kalman filter, are used in conjunction with a coherent receiver to measure frequency noise spectrum of a photonic crystal cavity laser with less than 20 nW of fiber-coupled output power. The extended Kalman filter is also used to recover a 28 GBd DP-16 QAM signal where a decision-directed phase-locked loop fails.

“…Heterogeneous integration by means of molecular or adhesive die-to-wafer bonding provides a scalable approach to integrate III-V opto-electronic components on the silicon photonics platform. Several types of laser sources have been realized on this platform, including single wavelength distributed feedback lasers [11][12], multi-wavelength lasers [13] and widely tunable lasers [7,14,15,16]. In this paper we present a novel type of widely tunable laser.…”

A heterogeneously integrated widely tunable III-V-on-silicon ring laser with unidirectional operation is demonstrated. 40 nm tuning range (from 1560 nm to 1600 nm) is obtained using the Vernier effect between two ring resonators incorporated in the ring laser cavity. Unidirectional operation is obtained by integrating a DBR reflector coupling the clockwise and counterclockwise mode of the ring laser cavity. Unidirectional operation is obtained over the entire tuning range with about 10 dB suppression of the clockwise mode. The laser linewidth is lower than 1 MHz over the entire tuning range, down to 550 kHz in the optimum operation point. The waveguide coupled output power is above 0dBm over the entire tuning range.
