Integral Tunable
Laser Assembly PPCL300

Low-noise lasers for
sensing and T&M applications typically were low-volume,
expensive and had limited performance. The PPCL300 tunable laser solves
this issue. Based on a volume-manufactured Telecom laser, the PPCL300
provides performance, quality and reliability at a reasonable price.
The 1550nm external cavity laser (ECL) design has an intrinsic
linewidth of 10kHz and very low phase noise down to the Hz range.
Achievable output power (up to 18dBm) and wavelength range (up to 60nm)
were previously unavailable. The device provides several agility
features, such as fast frequency jumps, single-mode frequency
modulation (up to 250GHz) and full band scans. In addition, analogue FM
and AM modulation inputs are available as well as an integrated DAQ..

Single Photon
Detectors for R&D of Quantum Technologies
Single Photon Detectors
are a vital component for registering very low
light as required for R&D of Quantum
Technologies. The PGA-308 is a SPAD which detects single
photons in the wavelength range of 0.95 to 1.6um. It is
fiber-pigtailed with a standard integrated 3-stage TE cooler, to
allow operation at -50°C without external cooling, in
a 6 pin TO-8 can. When specifically used for single photon
counting applications it is also available in a ultra-high sensitivity
version with dark count rate of 10 KHz or less at a detection
efficiency of 20%.
