Abstract
The frequency detuning-linewidth characteristics of the mode-locked frequency of a monolithic, passively mode-locked laser at millimeter wave frequency have been investigated. By changing the applied biases to the gain and absorber sections, a tuning range of about 20 MHz was observed at a mode-locked frequency of 47.61 GHz, while keeping the mode-locked linewidth to below 20MHz. The gain current variation needed for this tuning range is about 20 mA, while the absorber bias voltage affects the tuning only weakly.
