摘要

我们确定了光相位调制可以由线性域的强度变化引起的情况。特别地，对于标量双光束进双光束出的空间单一系统(分束器)，我们发现通过改变输入光束的强度比可以改变输出光束之间的相位差。利用这一原理，我们表明，在线性光学中(即使在非常低强度的情况下)，可以通过空间强度调制引入二维空间相位轮廓，从而影响随后光束的传播和远场分布。

Intensity-induced phase in linear optics.

We identify situations where optical phase modulation can be induced by intensity variations in the linear domain. In particular, for scalar two-beam in and two-beam out spatial unitary systems (beam splitters), we find that the phase difference between the output beams can be altered by changing the intensity ratio of the input beams. Utilizing this principle, we show that in linear optics (even in a very low-intensity regime), it is possible to introduce a two-dimensional spatial phase profile by spatial intensity modulation, thus affecting the propagation and far-field distribution of the ensuing beam.
