Detuned-loading effect
WebNov 1, 2013 · The effect of phase-sensitive optical feedback is directly visible from Fig. 2, ... Detuned loading is realised in a coupled cavity laser system by coupling a passive cavity to the active semiconductor laser such that frequency-dependent losses with a periodicity of the free-spectral range of the passive cavity are introduced. WebWe show that because of physical effects unique to lasing action in a semiconductor (a detuned gain spectrum leading to amplitude phase coupling of the lasing field 8) several …

WebJul 16, 2024 · 16) The detuned-loading effect was utilized to enhance MBW of directly modulated distributed Bragg reflector lasers.17) Mieda et al.18) applied a direct modal gain modulation scheme to inhibit the response degradation, pushing the MQW up to 50GHz. Matsui et al.19) demonstrated MBW of 55GHz. Vertical-cavity surface- WebNov 30, 2015 · This is because the detuned loading effect is maximized at this limit as the in-phase condition between the lights reflected from the PBR and anti-reflection (AR) coated facet of the gain medium is satisfied. Thus, by using this method together with conventional wavelength-locking algorithm, we can operate this ECL with minimum chirp at any ...
WebDec 30, 2024 · In the red-detuned region, γ r is enhanced and α is reduced, so the whole critical feedback value R c r i t is improved. In the blue-detuned region, all the trends are opposite, R c r i t is declined. The detuned loading effect on γ r and α is the main reason for the high feedback tolerance of a red-detuned DBR laser. WebNov 21, 2024 · The detuned-loading effect increases the effective differential gain and relaxation oscillation frequency by using the negative feedback of the Bragg grating …
WebWe then operate this ECL with minimum chirp by tuning the lasing mode to the longer wavelength limit of the stable operation region. This is because the detuned loading effect is maximized at this limit as the in-phase condition between the lights reflected from the PBR and anti-reflection (AR) coated facet of the gain medium is satisfied.
