PICEL^® Technology

PIC’s optically pumped PICEL^® (Photonic Integrated Cavity Emitting Laser) technology-based platform, represents the first compact OEM packaged commercialization of membrane external-cavity surface-emitting (MECSEL) laser technology, promising broad wavelength flexibility and close to quantum-noise-limited performance.

WhisperIT PICEL^® offers the wavelength coverage from 488nm to 1200nm. This includes 532nm-594nm where the direct diode lasers cannot reach. The WhisperIT PICEL^® is part of the family of the semiconductor disk lasers (SDLs) or vertical-external-cavity surface-emitting lasers (VECSELs). Optically pumped VECSELs can generate many watt output power in the wavelength regime ranging from 650 nm to more than 2.2 μm using quantum-well (QW) and quantum-dot (QD) structures. In contrast to diode-pumped solid-state lasers, a much broader range in operation wavelength can be reached in an MECSEL and still maintain low noise performance. MECSEL covers the same wavelength range as optically pumped semiconductor laser (OPSL) because similar semiconductor material is used offering good beam quality at high power.

MECSELs takes advantage of OPSL’s QW gain structure and improves its cooling by direct cooling on QW. As shown in figure 1, the heat generated in QW goes directly to heat spreaders in MECSEL vs OPSL where the heat goes through DBR before reaching heat spreader/heat sink. Therefore, much higher output power can be realized in the MECSEL compared to the OPSL. MECSEL manufacture process is based on the established semiconductor wafer process where many MECSEL chips are made in the wafer scale. This translates into lower manufacture cost.
