A high-power vertical-cavity surface-emitting laser(VCSEL) with a non-closed structure is reported,which resolves the problems such as gold bonding,heat dissipation and coating electrode for the conventional VCSELs.The processing is simplified,some device damage caused by the processing is avoided and the current injection efficiency is also improved.The VCSEL device can produce the maximum continuous-wave optical output power of 46 mW at room temperature.The lasing wavelength is 849.5 nm and the full-width...
