A laser source includes a first laser device configured to generate a first laser beam having a first wavelength, a second laser device configured to generate a second laser beam having a second wavelength, which is different from the first wavelength, and a non-linear crystal configured to receive simultaneously the first and second laser beams and to generate a third laser beam that has a third wavelength, which is larger than each of the first and second wavelengths. The non-linear crystal has a length and a width, and a variable poling period is distributed across the width so that the third wavelength varies within a given wavelength range based on an incident position of the first and second laser beams along the width of the non-linear crystal.

Tunable mid-infrared laser source and method

The present invention relates to precision linewidth control and frequency measurements of continuous wave lasers for the near to far IR spectral regions, precision frequency synthesizers and exemplary applications in molecular detection. Methods and systems are disclosed for simultaneous line narrowing of cw lasers, as well as referencing the desired emission wavelength to a frequency comb laser.

Methods for precision optical frequency synthesis and molecular detection

A reconfigurable optical device for wavelength-division multiplexing networks, comprising two waveguides (A, B) parallel to each other, with two-dimensional confinement, coupled by a bi-directional coupler (C), suitable to selectively drop one and only one of the channels composing the Wavelength-Division multiplexing signal (WDM); the device is reconfigurable as, by appropriately varying the wavelength of the combined pumping beam inside a first waveguide (A), any channel forming the WDM signal can be dropped.
