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- 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. multiple of net income
