Abstract

A squeezed light generator (SLG) for generating squeezed light (SQL) is disclosed, said squeezed light generator (SLG) comprising: -a waveguide (WG) being arranged to receive fundamental wavelength laser light (FWL), the waveguide(WG) comprising a second harmonic generator (SHG) for generating second harmonic light (SHL) from the fundamental wavelength light (FWL), -an optical cavity (OC) resonant for both fundamental wavelength light (FWL) and the second harmonic light (SHL), the optical cavity (OC) being arranged to receive the second harmonic light (SHL), and -a parametric down converter (PDC) arranged inside said optical cavity (OC), the parametric down converter (PDC) being adapted for generating said squeezed light (SQL) using said second harmonic light (SHL). Also, a method for generating squeezed light (SQL) is disclosed.
