VCSELs and VCSEL arrays

Share this on social media:

Princeton Optronics has announced the start of high volume mass production of single emitters and small arrays for autofocusing in cameras for cell phones and tablets.

The VCSELs array offered by the company presents itself as an easy choice as a replacement to an IR-LED in any active optical sensor because of its small form factor, high directionality and better electrical-to-optical conversion efficiency. The VCSELs demonstrate more than 63 per cent wall plug efficiency and can operate at temperatures as high as 100ºC. The VCSEL array allows for smaller, more cost effective packages with lower power consumption and longer range because of narrower native divergence. 

Single emitters can reach output powers from several mWs to several Watts in continuous mode, and an order of magnitude more in pulsed mode while maintaining efficiencies. Single emitters and arrays are offered in die sizes from 190x190um up to 500x500um and are offered at 850 and at 940nm.
