摘要
Nondegenerate mirrorless four-wave mixing oscillation with frequency tunability is proposed in nonlinear waveguide of the third-order nonlinearity such as silicon waveguide) by using two different spatial modes. As low as ˜2 W threshold power is obtained in several centimeters long waveguide. In one aspect, a method includes propagating a first wave along an axis of a multimode waveguide in a forward direction, the first optical wave having a first frequency; propagating a second wave along the axis of the multimode waveguide in a backward direction, the second wave having a second frequency; the waveguide configured to support multiple modes, including at least a fundamental mode and a second mode; and the propagating the first wave occurs at a same time as the propagating the second wave to generate a third wave in the forward direction having a third frequency and fourth wave in the backward direction having a fourth frequency.
