| 摘要 |
<p>An optical modulator (10) for modulating light (12) with an electrical signal, the modulator (1) comprising: an optical cavity (31), for enhancing an optical field of said light in a first mode (32) , an electrical input for receiving an electrical signal, a transformer (36) associated with said cavity (31) and with said electrical input for transforming light (12) within said optical field into a second mode (32) substantially orthogonal to said first mode (32), in accordance with said electrical signal, and an selective output coupler (38) associated with said optical cavity (31), to couple said second mode (32) to an output (26), thereby to provide, at said output (26), light (12) modulated in accordance with said electrical signal. Also disclosed is an internally modulated laser (37).</p> |
