克尔介质中的横模耦合

Transverse-mode coupling in a Kerr medium

J. M. Courty, A. Lambrecht

摘要:

分析了光腔中克尔介质中的非线性横模耦合对双稳态和各种量子噪声抑制的影响。即使对于与腔模完全匹配的输入光束,非线性耦合也会在输出光束的波动中产生过量的噪声。强度压缩似乎是特别强大的模式耦合,而正交压缩更敏感。然而,它是可能的,找到一个模式的正交压缩不受耦合。

英文摘要:

We analyze nonlinear transverse mode coupling in a Kerr medium placed in an optical cavity and its influence on bistability and different kinds of quantum noise reduction. Even for an input beam that is perfectly matched to a cavity mode, the nonlinear coupling produces an excess noise in the fluctuations of the output beam. Intensity squeezing seems to be particularly robust with respect to mode coupling, while quadrature squeezing is more sensitive. However, it is possible to find a mode the quadrature squeezing of which is not affected by the coupling.
