OPTICAL DEVICE HAVING PARTIALLY BUTT-COUPLED LIGHT SENSOR
摘要
<p>An optical device includes a light-transmitting medium positioned on a base. The light-transmitting medium defines a waveguide. The optical device also includes a light sensor. The light sensor includes a light-absorbing medium positioned on the base. A portion of the waveguide ends at a facet such that a first portion of a light signal being guided by the waveguide passes through the facet and a second portion of the light signal bypasses the facet and remains in the light-transmitting medium. The light-absorbing medium is positioned such that the light-transmitting medium is between the light-absorbing medium and the base. Additionally, the light-absorbing medium is positioned on the light-transmitting medium such that the light-absorbing medium receives the first portion of the light signal that passes through the facet. Further, the light-absorbing medium is configured such that the second portion of the light signal is coupled into the light-absorbing medium.</p>
