ELECTRO-OPTIC MODULATOR AND ELECTRO-OPTIC DISTANCE-MEASURING DEVICE |
摘要 |
<p>An electro-optic modulator comprises a waveguide (2) of a nonlinear optical material and an electrode line (3) for generating an electrical field in a modulating region (17) of the waveguide (2) when a voltage is applied to the electrode line (3), thereby modulating light passing through the waveguide (2). Therein
€¢ the forward electro-optic response of the modulating region (17) is the same as the backward electro-optic response; and
€¢ the electro-optic response has a band-pass or a low-pass characteristic. A distance measuring device comprises a light source (101) emitting light, and such an electro-optic modulator arranged such that the emitted light passes through the electro-optic modulator in a first direction before being emitted from the distance measuring device, and after being reflected from a target passes through the electro-optic modulator in a second direction which is opposite to the first direction.</p> |
