1550nm continuous-wave laser

DTU will buy a 1550nm continuous-wave laser.

Kgs. Lyngby

Low phase noise fiber laser at 1550 nm delivering 40 mW of power in a continuous-wave beam. The laser is used within the QTREX continuous-variable quantum key distribution system. The receiver lasers must have thermal as well as piezo tuning to control the wavelength close to the transmitter laser (~10 MHz).

The minimum requirements for the product are:

- Low phase noise < 100 Hz linewidth

- Relaxation oscillation relative intensity noise peak < 1 MHz

- No relative intensity noise peaks in the spectrum from 1 MHz to 200 MHz

- Wavelength: 1550.12 nm thermally tunable by 1 nm.

- Beat of two lasers shall be stable within 30 MHz during 1 hour

- Laser output power: 40 mW

- Polarization maintaining fiber output

Small form-factor that can be integrated into a system: <= 150mm x 70 mm x 20mm

Proven operation in the QTREX continuous-variable quantum key distribution system allows for minimal costs for component testing and integration

Component from a European supplier to establish a European supply chain for the quantum key distribution devices.

The low phase noise is required to achieve good performance of our device. The frequency range of interest is 1 to 200 MHz and we require shot-noise limited operation at the respective power levels in the transmitter and receiver. Thermal tuning and frequency stability is required to tune the beat between two lasers into detection range and stay within it for a long time. The laser shall be integrated into a system which requires the specified dimensions. In a market search no other supplier fulfilling these requirements were found.

The laser shall be proven to work for our application to avoid additional costs and reduce risks. It shall be used within the European Quantum Communication Infrastructure which aims at supporting a European supply chain.
