Abstract
We investigate the decision threshold adjustment in a proposed all-optical decision gate consisting of two gain-clamped
semiconductor optical amplifiers (GCSOA’s). The GCSOA discussed in this letter is constructed with a gain section and two
passive distributed Bragg reflectors (DBR’s) on each side. We derive a model for current-induced or temperature-dependent
Bragg reflectance variation, with which the threshold current density and the oscillating power at DBR wavelength are
described. This model allows a possible numerical prediction for decision threshold adjustment induced by current injection or
temperature variation.
