  Polarization Stabilized Wavelength-Swept Laser: Lambda-Sweep ™

  SEMICONDUCTOR LASERS

General Photonics’ wavelength-swept laser is a high sweep rate OEM laser source for fibre sensor, OCT, and spectrum analysis development applications.

The laser’s wavelength can be swept at a rate of up to 16 kHz across a spectral range of up to 150 nm, with an output optical power of up to 20 mW. A power monitoring output is included to indicate the instantaneous laser output power at each wavelength. Other laser health parameters, such as laser average power, driving current, and chip temperature, are also provided via a digital interface. Finally, the laser incorporates automatic polarization optimisation to guarantee long term stability.

The WSL-001 is available with either a linearly polarized output (aligned to the slow axis of a PM fibre) or a depolarised output. It can also come equipped with a built-in variable optical attenuator (VOA) and a sweep monitor that provides two ?-trigger (TTL) signals to indicate the exact starting and ending wavelengths of each wavelength sweep.

The ?-triggers can be used with a sweep profile lookup table to pinpoint the absolute frequency or wavelength of the laser at each instant during a wavelength sweep. This combination of features makes it easy to integrate the tunable laser into sensor interrogators, optical coherence tomography (OCT) equipment, spectrum analysis equipment, and general purpose test and measurement instruments

Applications:

• Fiber sensor interrogation
• Optical Coherence Tomography (OCT)
• Medical imaging
• Test & measurement
• Spectrum analysis
• R&D
