We use the two-dimensional (2-D) scattering matrix method (SMM) to analyze the slot characteristics in slotted single-mode semiconductor lasers and compare the results with those calculated by the… (More)
We present a black-box four wave mixing based bit-rate-flexible phase sensitive amplifier and use it in the first demonstration of 40 Gbit/s DPSK phase regeneration.
In this study, a phase-preserving limiter based on injection locking a semiconductor laser is fully investigated as an amplitude limiter for 10 Gb/s constant envelope phase encoded signals. A… (More)
The authors demonstrate the generation of a highly coherent multicarrier signal that consists of eight clearly resolved 10.7-GHz coherent sidebands generated within 3 dB of the spectral envelope peak… (More)
We show for the first time 100 Gbit/s total capacity at 2 µm waveband, using 4 × 9.3 Gbit/s 4-ASK Fast-OFDM direct modulation and 4 × 15.7 Gbit/s NRZ-OOK external modulation, spanning a 36.3 nm wide… (More)
The authors present the design and characterization of a novel integrated two-section discrete mode index patterned diode laser source. The two slotted regions etched into the laser ridge waveguide… (More)
We report a novel system for simultaneous carrier recovery and frequency symmetric signals generation from a NRZ-BPSK input by exploiting FWM in HNLF for phase sensitive amplification.
Introduction: Attainment of the minimum achievable laser diode lin width with the least associated level of device complexity and lowest co mp nent cost are critical for realising many single… (More)
We report on monolithic devices with linewidths as low as 138kHz which operate in a narrow linewidth, single mode with high sidemode supression ratio over a wide temperature tuning range of −10°C to… (More)
