چکیده
The first integrated SGDBR laser/Semiconductor Optical Amplifier-MachZehnder modulator transmitter is presented. Devices have 3dB bandwidth ranging from 1318GHz corresponding to electrodes lengths that range between 200-300um long. This corresponds to a Vpi of 4.8-6.2V Fig. 1 MZ-SOA-SGDBR layout

Field modulated wavelength converters
We demonstrate 10Gbit/s operation of two different types of monolithic photocurrent driven wavelength converters (PD-WC). These photonic integrated circuits use a Semiconductor Optical Amplifier (SOA)-PIN photodetector receiver to drive an Electro-absorption (EA), or Mach-Zehnder (MZ) modulator that is integrated with a SGDBR tunable laser. We demonstrate improvements in optical bandwidth, inse...
متن کاملSampled-Grating DBR Laser-Based Analog Optical Transmitters
Sampled-grating distributed Bragg grating (SGDBR) laser-based widely tunable optical transmitters are investigated for application in high-performance analog links. More than 45 nm tuning range, 40 dB sidemode suppression ratio, and peak relative intensity noise below 153 dB/Hz is measured. SGDBR lasers integrated with semiconductor optical amplifiers and electroabsorption modulators (EAMs) are...
متن کاملDemonstration of Monolithically-Integrated InP Widely-Tunable Laser and SOA-MZI Wavelength Converter
The first monolithically integrated widely tunable wavelength converter, consisting of a Sampled-Grating Distributed-Bragg-Reflector laser and a semiconductor optical amplifier-based Mach-Zehnder interferometer, is reported. Static extinction ratios better than 19dB and 13 dB using electrical and optical control, respectively, were measured over a 22nm laser wavelength range.
متن کاملIntegrated Tunable Transmitters for Wdm Networks
The integration of widely-tunable sampled-grating lasers with semiconductor optical amplifiers and either electroabsorption or Mach-Zehender modulators has been successful in creating high-performance optical transmitters. Details of this performance as well as recent advances in this technology will be reviewed in this paper. Introduction The desire to reduce operational costs with a universal...
متن کاملHybrid Integrated Tunable Optical Transmitter Subsystem on a Chip
The need for tunable optical transmitters in optical networking is growing at a rapid rate. A tunable optical transmitter is the combination of a tunable laser, an isolator, and a modulator. Although today lasers and modulators could be integrated together on a single chip, an integrated component of this type would not be useful because the absence of an isolator between the two elements would...
