Optical Bistability and Nonlinear Gain in a 1550 nm-Vertical Cavity Semiconductor Optical Amplifier (VCSOA) with High On-Off Contrast Ratio

Antonio Hurtado, Ian D. Henning, M.J. Adams

This paper reports on the experimental observation of power and wavelength optical bistability (OB) and nonlinear gain in a 1550 nm- vertical cavity semiconductor optical amplifier (VCSOA) biased just below threshold and operated in reflection. Two different shapes of power and wavelength OB and nonlinear gain, anticlockwise and clockwise, have been experimentally observed, both with high on-off contrast ratio.

Optical bistability in vertical-cavity semiconductor optical amplifiers

Pengyue Wen, Michael Sánchez, Matthias Groß +1 more

We present an overview of the properties and applications of optical bistability in vertical-cavity semiconductor optical amplifiers (VCSOAs). The basic physics and analytical models of this optical nonlinearity are discussed. Experimental results obtained from a VCSOA operated in the 850 nm wavelength region are presented. 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 muW when the device is biased at 98% of its lasing threshold. Numerical simulations based on the Fabry-Perot resonator model and rate equations we developed show good agreement with our experimental observations. In addition, a low input intensity high contrast (10:1) optical and gate and 2R regeneration are demonstrated. We believe that bistable VCSOAs can significantly advance the prospect of a dense two-dimensional array of low-switching-intensity all-optical logic and memory elements.

Observation of bistability in a Vertical-Cavity Semiconductor Optical Amplifier (VCSOA)

Pengyue Wen, Michael Sánchez, Matthias Groß +1 more

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 its lasing threshold. We also numerically simulate the optical bistability and obtain good agreement with our experimental observations. Bistable VCSOAs significantly advances the prospect of dense 2-D array of low switching-intensity all-optical logic and memory elements.
