摘要： An optical device having one or more optical components is disclosed. A waveguide extends from an optical component to a testing port configured to receive a light signal from a position over the optical device and to insert the light signal into the waveguide. In some instances, the testing port is configured to receive a light signal from the waveguide and to direct the light signal to a location over the optical device. The optical device can be positioned on a wafer before being separated from the wafer. The waveguide can extend from an optical component over the perimeter of the optical device such that the testing ports are located outside the perimeter of the optical device.

摘要： An optical device includes a light-transmitting medium on a base. The light-transmitting medium at least partially defines a free propagation region through which light signals travel. A reflective grating is positioned such that light signals can travel through the free propagation region and be received by the optical grating. The optical grating is configured to reflect the received light signal back into the free propagation region. The optical grating reflects the light signals such that light signals associated with different wavelengths separate as the light signals travel through the free propagation region. The portion of the light-transmitting medium that defines the free propagation region has a facet through with the light signals are transmitted. The grating includes a buffer layer between the facet and a reflecting layer that is configured to reflect the light signals received by the grating.

摘要： A method of forming an optical component includes forming a first mask on an optical component precursor. The first mask is formed with a plurality of waveguide portions extending from a common portion. Each waveguide portion is positioned so as to protect a waveguide region of the optical component precursor where a waveguide is to be formed. The method also includes forming a second mask between waveguide portions of the first mask. The resistance of the second mask to etching varies along at least one dimension of the second mask.

摘要： The optical device includes a waveguide on a base. The waveguide is configured to guide a light signal through a light-transmitting medium to a light sensor. The light sensor includes a sensor waveguide on the base. The sensor waveguide receives the light signal from the input waveguide. Additionally, the sensor waveguide includes a light-absorbing medium having an input side. The input side is interfaced with the light-transmitting medium such that at least a portion of the light signal received by the sensor waveguide travels through the input side of the light-absorbing medium upon being received by the sensor waveguide. The light-absorbing medium includes doped regions. One or more of the doped regions each extends from within the light-absorbing medium to the input side of the light-absorbing medium.
