PPCL100/200/300 Tunable Lasers

1527.6-1608.8 nm; Output Power 7-18 dBm; Tuning Range ≤60 nm; Spectral Linewidth 10 kHz Typical; Back-Reflection ≤-14 dBm; PER ≥18 dB

Pure Photonics’ PPCL100/200/300 tunable lasers are based on a volume produced integrable tunable laser assembly (ITLA) for the telecom market, ensuring performance, quality and reliability. All PPCL series devices are full-band tunable laser solutions, controlled through a digital interface, providing a very narrow linewidth (~10 kHz), significantly reduced low-frequency AM and FM noise and different operating modes in this low-noise setting.

Unique tuning control technology enables the lasers to access any desired frequency set-point in the tuning range (C-band, L-band or optionally up to 60 nm). With the lasers’ low-loss external cavity, the output power can be set as low as 7 dBm and as high as 18 dBm.

The Pure Photonics PPCL100/200/300 tunable laser solutions make a field proven, high-volume telecommunications laser suitable for the high-demanding applications that are typically addressed by hand-crafted custom solutions. Not only does the technology provide optical performance at-par with the existing solutions, it does so in an extremely small form-factor and a tuning range in excess of 35 nm.

Pure Photonics provides three base versions of the product (PPCL300, PPCL200, PPCL100), which all can be customized in output power performance as well as frequency range. Each version can be further enhanced by their available operating features, such as modulation, fast tuning etc. PPCL series low-noise tunable lasers can be provided as-is, with an evaluation system or integrated into either the PPCL500 (for PPCL100, PPCL200), PPCL550 (for PPCL300) or CoBrite enclosure.
