Abstract:

Photon pair generation is of great importance in photonic technologies such as quantum information and quantum communication. One way of generating correlated pairs is to use the nonlinear process of spontaneous-four-wave-mixing (SFWM). Nonlinear processes, however, need intense light to occur. Microring resonators and microcavities in photonic crystal slabs have the ability to confine laser light over micron-scale lengths, thereby producing large intensities. This makes them well suited for nonlinear pair-generation. However, in any realistic system, there is always loss present that can result in degraded operation of the device. In this talk, I present recent work on photon pair-generation in lossy coupled-cavity systems via SFWM. In particular, I will describe the effects of loss on pair generation brightness and multiple pair generation.
