OPTICAL DEVICE HAVING LIGHT SENSOR EMPLOYING HORIZONTAL ELECTRICAL FIELD |
摘要 |
<p>The device includes an optical waveguide on a base. The waveguide is configured to guide a light signal through a light-transmitting medium. A light sensor is also positioned on the base. The light sensor including a ridge extending from slab regions. The slab regions are positioned on opposing sides of the ridge. A light-absorbing medium is positioned to receive at least a portion of the light signal from the light-transmitting medium included in the waveguide. The light-absorbing medium is included in the ridge and also in the slab regions. The light-absorbing medium includes doped regions positioned such that an application of a reverse bias across the doped regions forms an electrical field in the light-absorbing medium included in the ridge.</p> |
