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. |
