Membrane external-cavity surface-emitting laser emitting at 1640  nm

Abstract

We fabricated and characterized a membrane external-cavity surface-emitting laser (MECSEL) emitting at 1640 nm. This is the first, to the best of our knowledge, description of this type of laser emitting at the long-wavelength telecommunication band. Double-sided diamond heat spreaders were used to efficiently dissipate heat. Emission producing 1.2 W of power was demonstrated. We suggest that optimization of the laser has the potential to increase generated power.

Thermal Behavior and Power Scaling Potential of Membrane External-Cavity Surface-Emitting Lasers (MECSELs)

“…The membrane external-cavity surface-emitting laser (MEC-SEL) architecture has recently emerged [1]- [3] to further expand the versatility of the larger class of semiconductor disk laser technology [4]- [6]. Similar to a vertical-externalcavity surface-emitting laser (VECSEL) architecture [7], the gain region in a MECSEL is made of a quantum well (QW) or quantum dot (QD) heterostructure, separated by barriers and grouped into several packages.…”

On the same line, the ability of MECSELs to achieve a broader wavelength tunability [11] and to implement a design optimized towards mode-locking operation [12] has been also demonstrated.…”

Growth and characterization of InP-based 1750 nm emitting membrane external-cavity surface-emitting laser

“…The structure without DBRs constitutes the gain element of the DBR-free laser, also called an MECSEL [19,20]. MECSELs and VECSELs both offer laser beams with high-power and high optical quality, but MECSELs offer a higher wavelength flexibility when compared with VECSELs [20,21].…”
