Abstract

In this paper, we report counter-clockwise, clockwise, and, for the first time to our knowledge, butterfly bistability in 1550 nm Vertical Cavity Semiconductor Optical Amplifiers (VCSOA). Bistable operation is experimentally observed for bias currents ranging from 66–122% of threshold with switching powers as low as 2 μW. These switching powers are two orders of magnitude lower than any previous results in 1550 nm VCSOAs. These switching powers are consistent with previous reports on optical bistability in 850 nm VCSOAs and provide an important step towards the realization of small footprint, low power optical logic/switching elements in the 1550 nm wavelength band.

Illustration of (1) explaining the existence of clockwise bistability in reflection mode VCSOAs. Solid curves represent higher bias-lower detuning case which generates counterclockwise hysteresis in Iref. Dotted curves represent lower bias-higher detuning case which generates clockwise hysteresis in Iref. The transition between these two regimes generates butterfly hysteresis.
