Photonic crystal optical parametric oscillator
We report a new class of optical parametric oscillators, based on a 20-μm-long
semiconductor photonic crystal cavity and operating at telecom wavelengths. Because the
confinement results from Bragg scattering, the optical cavity contains a few modes,
approximately equispaced in frequency. Parametric oscillation is reached when these high-
quality-factor modes are thermally tuned into a triply resonant configuration, whereas any
other parametric interaction is strongly suppressed. The lowest pump power threshold is …

… The first demonstration of an optical parametric oscillator using a photonic crystal
microcavity is promising for the future development of on-chip light sources for applications in
integrated quantum optics. … One photonic device in particular that scientists have been
trying to miniaturize and put onto a chip is the optical parametric oscillator (OPO), a source of
light where two beams, named the signal and idler, are generated from a pump beam by
nonlinear optics. Commercial and lab-built OPOs are usually on the scale of tens of …
