High-power 1.55 μm VCSEL arrays

The potential of the classical single-device vertical-cavity surface-emitting lasers (VCSEL) with various apertures of the buried tunnel junction was investigated. The power-current-voltage characteristics for different temperatures and the electrical to optical conversion efficiency (wall-plug effi...

Description
Summary:The potential of the classical single-device vertical-cavity surface-emitting lasers (VCSEL) with various apertures of the buried tunnel junction was investigated. The power-current-voltage characteristics for different temperatures and the electrical to optical conversion efficiency (wall-plug efficiency) of the VCSEL arrays were studied.
