Abstract: Embodiments herein describe combining multiple optical signals so these signals propagate in the same direction in the same optical mode and polarization. In one embodiment, the techniques discussed herein are used to combine a reference laser with a frequency comb so that supercontinuum generation can then be performed to increase the frequency range of the frequency comb so that it includes the frequency of the reference laser.

Abstract: Embodiments herein describe a path length adjuster for, e.g., adjusting the length of an optical cavity of a laser. In one embodiment, the path length adjuster includes a circulator element for ensuring unidirectional lasing. The path length adjuster may also include one or more focusing elements such as a focusing lens and/or a collimator which directs received laser light at a mirror. The mirror is mounted on an actuator that moves the mirror in a direction parallel with the propagation of the laser light, thereby increasing or reducing the length of the ring cavity.

Abstract: Embodiments herein describe using a birefringent element (e.g., a half-wave plate, full-wave plate, birefringent crystal, or metasurface) or a band-pass filter to reduce the laser line broadening induced by the soliton self-frequency shift. The birefringent element may a free space element that is part of the laser cavity. Due to dispersion, different frequencies (or colors) of light in the laser travel through the birefringent element at different speeds. This dispersion results in the birefringent element introducing slightly different polarization shifts for the different frequencies of light in the laser. When this light passes through a polarizer (which is set to filter out polarizations different from a desired polarization), the polarizer attenuates or extinguishes the frequencies that do not have the polarization of the design frequency of the birefringent element.
