At this wavelength, the largest hysteresis is expected to be obtained. Our wavelength working point is thus chosen to be λ = 1563.645 nm, corresponding to a change in the optical transmission of ∆T~ −2.3 dB, as shown in Fig. 2C.
WebApr 14, 2024 · The incorporation of 20% Al content in the DBRs opens an optical pumping window from 700 to 820 nm, where the excitation laser light can effectively reach the GaAs cavity above its bandgap while remaining transparent to the DBRs. This results in a substantially improved pump efficiency, a low lasing threshold, and a high thermal stability.
