Réimse cumarsáide optúil

The development direction of high speed, large capacity and wide bandwidth of optical communication requires the high integration of photoelectric devices. Is é an bunús a bhaineann le comhtháthú ná mionsamhlú feistí fótaileictreacha.

Úsáideann an córas tonnta éadroma chun faisnéis fuaime a tharchur. The laser generated by the laser becomes linearly polarized light after the polarizer, and then becomes circularly polarized light after the λ / 4 wave plate.
