Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper. The present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. Two equations were derived to calculate the noise and modulation response. Calcula...

A distributed balanced photodetector with high saturation photocurrent and excellent linearity has been experimentally demonstrated. Distributed detection is shown experimentally to be important for the high saturation photocurrents. High-speed photodetectors with high saturation photocurrents are essential for high performance analog fiber optic links. In externally modulated links, the link g...

Passive optical network topology has been widely adopted in access networks due to its low-cost and yet flexible network structure. To further promote the passive optical networks, the cost reduction of optical modules is critical. Relatively expensive combination of a conventional index-coupled distributed feedback laser diode (IC-DFB-LD) and an optical isolator is commonly used for passive op...

Abstract We report on the design, growth, fabrication, and performance of InAs/InP quantum dash (QD) multi-wavelength lasers (MWLs) developed by National Research Council (NRC) Canada. The key technical specifications investigated include optical RF beating spectra, relative intensity noise (RIN), phase each individual wavelength channel. Data bandwidth transmission capacity 5.376 Tbit/s 10.8 r...
