Current and frequency modulation characteristics for continuous-wave quantum cascade lasers at 9.06 μm.
We report the characteristics of current induced frequency modulation (FM) for two continuous-wave quantum cascade lasers (QCLs) at 9.06 μm. Both the frequency tuning rate and the phase shift between intensity modulation and FM are measured at different modulation frequencies from 10 Hz to 200 kHz. The frequency tuning rate of the QCLs depends on both the modulation frequency and amplitude. The...
متن کاملEnhanced Modulation and Noise Characteristics in 1.55 µm QD Lasers using Additional Optical Pumping
The modulation response, relative intensity noise (RIN) and frequency noise (FN) characteristics of quantum dot (QD) lasers are investigated theoretically in the presence of an external optical beam. Using small signal analysis of the rate equations for carriers and photons, it is demonstrated that by injecting excess carriers into the QDs excited state through optical pumping, the modulation r...
متن کاملEffect of neutron irradiation of MQW lasers to 1015n/cm2
1300nm edge-emitting multi-quantum-well lasers are the baseline choice for the optical transmitter in the CMS tracker optical links. The radiation environment is expected to be ~10Mrad and ~1014(neutron-equivalent)/cm2 over ten years. Lasers from four manufacturers have been irradiated in naked die form with neutron fluences of ~2x1014n/cm2. One laser type was also irradiated in a fully package...
متن کاملThermal Effects and Small Signal Modulation of 1.3-μm InAs/GaAs Self-Assembled Quantum-Dot Lasers
We investigate the influence of thermal effects on the high-speed performance of 1.3-μm InAs/GaAs quantum-dot lasers in a wide temperature range (5-50°C). Ridge waveguide devices with 1.1 mm cavity length exhibit small signal modulation bandwidths of 7.51 GHz at 5°C and 3.98 GHz at 50°C. Temperature-dependent K-factor, differential gain, and gain compression factor are studied. While the intrin...
متن کاملImproved ground-state modulation characteristics in 1.3 μm InAs/GaAs quantum dot lasers by rapid thermal annealing
We investigated the ground-state (GS) modulation characteristics of 1.3 μm InAs/GaAs quantum dot (QD) lasers that consist of either as-grown or annealed QDs. The choice of annealing conditions was determined from our recently reported results. With reference to the as-grown QD lasers, one obtains approximately 18% improvement in the modulation bandwidth from the annealed QD lasers. In addition,...
