Optical bistability in a Vertical-Cavity Semiconductor Optical Amplifier (VCSOA): pulsed input
We report experimental observations of optical bistability in a vertical-cavity semiconductor optical amplifier subject to an external pulsed input. Results show that the nonlinear transition exists with 1ns-duration pulsed input. © 2003 Optical Society of America OCIS codes: (190.1450) Bistability; (200.4660) Optical logic
متن کاملAll-Optical 2R Regeneration Using a Non-Linear Vertical Cavity Semiconductor Optical Amplifier
All-optical 2R logic regeneration is demonstrated using a vertical cavity semiconductor optical amplifier. The optical switching threshold is 1 μW, with 10 dB gain and >6:1 (8dB) extinction ratio. Performance limits are also discussed. ©2003 Optical Society of America OCIS codes: (190.1450) Bistability; (200.4660) Optical Logic; (250.5980) Semiconductor Optical Amplifiers; (230.4320) Nonlinear ...
متن کاملObservation of bistability in a Vertical-Cavity Semiconductor Optical Amplifier (VCSOA).
We report, the first time to our knowledge, an observation of optical bistability in a Vertical-Cavity Semiconductor Optical Amplifier (VCSOA) operated in reflection mode. Counterclockwise hysteresis loops are obtained over a range of initial phase detuning and bias currents. One hysteresis loop is observed experimentally with an input power as low as 2 ìW when the device is biased at 98% of it...
متن کاملGaInNAs-based Hellish-vertical cavity semiconductor optical amplifier for 1.3 μm operation
Hot electron light emission and lasing in semiconductor heterostructure (Hellish) devices are surface emitters the operation of which is based on the longitudinal injection of electrons and holes in the active region. These devices can be designed to be used as vertical cavity surface emitting laser or, as in this study, as a vertical cavity semiconductor optical amplifier (VCSOA). This study i...
متن کاملTunable ultraslow light in vertical-cavity surface-emitting laser amplifier.
We report the experimental demonstration of tunable ultraslow light using a 1.55 um vertical-cavity surface-emitting laser (VCSEL) at room temperature. By varying the bias current around lasing threshold, we achieve tunable delay of an intensity modulated signal input. Delays up to 100 ps are measured for a broadband signal with modulation frequency of 2.8 GHz. With a VCSEL design optimized for...
