Fixed-point frequencies analysis of monolithic 10 GHz repetition rates AlGaInAs multiple quantum-well laser diodes

We report the first conducted measurements of the fixed-point frequencies on a 10 GHz repetition rate mode locked laser diode functioning at 1.55 μm wavelength. The measurements show that four unique laser parameters can be modulated to independently control the combline offset frequency, V
₀
, and comb spacing, f
