“…The low entry costs of a generic model make it attractive for introducing photonic ICs also to non-telecom markets, like: medical and bio-imaging [8], optical data-handling [9], fiber sensor readouts [11], THz applications [12]. Examples of photonic ICs fabricated via MPW runs on InP-based platforms are presented in Figure. interferometer [9], (c) multichannel transmitter [10], (d) wavelength meter for sensing [11].…”

In this paper we report on the progress in the development of modelocked ring lasers that are integrated on a single chip in the InP/InGaAsP material system. With the current optical integration technology it is possible to integrate quantum well optical amplifiers, phase modulators and passive optical components such as waveguides, splitters and spectral filters as standardized building blocks on a single chip. Using such standardized components a number of passively modelocked ring laser devices have been realized in a standardized fabrication process. Results from a few of these devices are presented here. We have observed a record width of the frequency comb from a modelocked quantum well ring laser operating at a 20 GHz repetition rate. The optical coherent comb is centered around 1542 nm and has a 3 dB bandwidth of 11.5 nm. A minimum pulse width of 900 fs was observed. A second device that is highlighted is a modelocked ring laser with a 2.5 GHz repetition rate. Its 33 mm long cavity is fitted onto a chip of 2.2x1.9 mm 2 . One of the goals of this work is to make such designs available in device libraries for use in more complex integrated optical systems using standardized technology platforms.

Abstract:We report a novel narrow-linewidth WDM transmitter operating at 10 Gbps per transmission channel with 275 kHz optical linewidth. The device, which integrates an AWGbased laser using selective DBR-mirrors with a Mach-Zehnder modulator array, has been fabricated in a multi-project wafer run in a generic InP-based foundry process. IntroductionIn this paper we present a novel 8-channel multiwavelength transmitter (MWT) with very narrow linewidth, realized in a generic indium phosphide (InP)-based foundry process [1,2]. The generic foundry approach allows for rapid prototyping at low cost, by participating in so called Multi-Project Wafer runs. These are fabrication runs in a standardized foundry process in which a number of different designs are combined on a single wafer, thus sharing the cost of a run. This approach has been practiced for a few years in silicon photonics, but recently it has become also available for advanced InP-based integration processes [3,4].The MWT reported here is based on the operational principle of a linear arrayed waveguide grating-based laser (AWGL) [5,6] and is an alternative design to the MWTs presented in [7,8]. The wavelength-selective mirrors, implemented as DBR-based gratings, will prevent lasing of the source in unwanted AWG orders, thus guaranteeing operation in the central free spectral range [6]. The schematic and a photograph of the fabricated circuit are presented in Fig. 1. The cavity of the AWGL is formed between the highly reflective (HR) coated cleaved facet of the chip and the DBR grating. Because the DBR mirrors can be positioned freely on the chip, the length of the laser cavity can be reduced and the longitudinal mode spacing can be controlled. Recently reported on-chip mirrors, multi-mode interference reflectors [9] also provide such flexibility, but are broadband and therefore cannot be used as wavelength selective filters. In our configuration employing DBR gratings, we obtain single mode operation without mode hops and a narrow linewidth thanks to the relatively long extended cavity of the AWGL. The sources are easier to drive, as compared to traditional AWGLs. In addition, the tuning precision can be enhanced by introducing phase elements (PH) within the resonant cavity.
