| description | The invention discloses an orbital angular momentum and polarization coupling degenerate optical resonant cavity which is simple in structure and needs few optical elements, a coated glass sheet or awave plate is ingeniously used as a cavity mirror, and modulation and coupling of intracavity photon orbital angular momentum and polarization are achieved through liquid crystal molecules. Photons inthe cavity do not pass through air, the whole degenerate optical resonant cavity is a whole, random phase change caused by jittering is avoided, and the system is more stable. In addition, the voltage at the two ends of the liquid crystal molecules can be adjusted through an external voltage source, and then modulation coupling parameters of photon orbital angular momentum and polarization in thecavity are adjusted.
本发明公开了一种轨道角动量及偏振耦合简并光学谐振腔，该谐振腔结构简单，所需光学元件少，巧妙利用镀膜玻璃片或者波片作为腔镜，通过液晶分子实现腔内光子轨道角动量与偏振的调制与耦合。腔内光子不经过空气，整个简并光学谐振腔是一个整体，不会因为抖动导致相位随机变化，系统更加稳定。此外，通过外接电压源可以调节液晶分子两端的电压，进而调节腔内光子轨道角动量与偏振的调制耦合参数。 |
