A proposal for highly tunable optical parametric oscillation in silicon micro-resonators

Abstract

Abstract:We propose a novel scheme for continuous-wave pumped optical parametric oscillation (OPO) inside silicon micro-resonators. The proposed scheme not only requires a relative low lasing threshold, but also exhibits extremely broad tunability extending from the telecom band to mid infrared.

Nonlinear silicon nanophotonics for mid-infrared applications

“…These results provide a foundation for the construction of silicon-based room-temperature mid-IR light sources including tunable chip-scale parametric oscillators [16][17][18], optical frequency combs [19], and supercontinuum generators [20]. In this manner, silicon nanophotonic technology may be extended to an entirely new class of mid-IR applications [4,5] including biochemical detection, environmental monitoring, and freespace communication, in which an integrated on-chip platform can be of significant technological benefit.…”

“…( ) and is thus directly proportional to the dispersion coefficient (note that at high power levels the phase mismatch becomes power dependant; see (Lin et al, 2008)). For micro-ring resonator structures, Eq.…”

“…In resonators, the linear phase matching condition for the propagation constants is automatically satisfied as the resonator modes are related linearly by : = m/R Lin et al, 2008 Lin et al, 2008). We define the region where four-wave mixing is possible through the relation 33 3 /2 rr Q ωωω ω Δ= − < , such that the generated idler is within the bandwidth of the resonance.…”

“…This extraordinary result comes from the low dispersion of the resonator, which permits appreciable phase matching over a broad bandwidth at low power. However, it is important to note that four-wave mixing can always be accomplished in an anomalous dispersion regime given a sufficiently high power (Lin et al, 2008).…”

Nonlinear Group IV photonics based on silicon and germanium: from near-infrared to mid-infrared

“…Many nonlinear effects have been reported recently in silicon photonics touching the mid-IR wavelength range [60,61,106,108,114,115,[135][136][137][138][139][140][141][142][143][144][145]. It is noted that most of them address the short-wavelength end of the mid-IR, from 2 to 2.5 μm, which is mainly the short-wave IR [144] or transition from near-IR to mid-IR.…”
