Sub-harmonic actively mode-locked VCSEL module was successfully fabricated by fixing a concave mirror using UV cure adhesive. Unique double-path resonance configuration was found effective to relax the mirror misalignment tolerance.
By optimizing reflectivities of VCSEL and external mirror of composite resonator using a VCSEL and an external concave mirror, high speed mode-locking with a repetition rate of 24 GHz and a low threshold of 0.7 mA was simultaneously realized.
To realize low power consumption and high-speed repetition rate mode-locked laser, we designed a VCSEL with an external concave mirror. Repetition rate as high as 31 GHz and threshold current as low as 1 mA were simultaneously demonstrated with sub-harmonic active mode-locking.
We have demonstrated mode-locking using a VCSEL and a concave mirror with new double-path resonance scheme. This scheme was found to provide significant improvement in the position tolerance between the VCSEL and the concave mirror.
A very low threshold current lasing operation was demonstrated with a composite resonator VCSEL using a concave external mirror. Sub-harmonic active mode-locking produced light output with a repetition rate of 10.56 GHz.
