摘要： A photodetector is realized which does not need an additional circuit for an inspection and may perform a characteristic evaluation inspection of optical input and electrical output such as optical sensitivity and OE characteristics of a photodetector alone with respect to wavelength and temperature dependent characteristics. A photodetector (400) is provided in which light absorption layers (414 and 415) are formed on a semiconductor substrate, the photodetector (400) detects signal light incident on the light absorption layers (414 and 415) from a direction in a substrate surface of the semiconductor substrate, and the light absorption layers (414 and 415) have a portion not covered by an electrode (417) for photocurrent detection connected with the light absorption layers (414 and 415) in a case where the substrate surface of the semiconductor substrate is seen from a direction from an outside of the substrate surface.

摘要： The invention relates to a method for producing a polarization converter comprising the following steps: producing a first converter element (11) having a base side (111), an upper side (112) extending parallel to the base side (111) and a longitudinal side (114) oriented obliquely at an angle ε1 to the base side (111) or a curved longitudinal side; producing a second converter element (12) comprising a base side (121), an upper side (122) extending parallel to the base side (121) and a longitudinal side (124) oriented obliquely at an angle ε2 to the base side or a curved longitudinal side; disposing the first and the second converter element (11, 12) in series in such a way that the obliquely oriented or curved longitudinal sides (114, 124, 1240) point in opposite directions, wherein the first converter element (11) has a length L1 and its upper side (111) has a width w1 measured perpendicular to the longitudinal direction of the first converter element (11), and the second converter element (12) has a length L2 and its upper side (111) has a width w2 measured perpendicular to the longitudinal direction of the second converter element (12). According to the invention, the production of the first and second converter element (11, 12) consists of determining different lengths L1 and L2 and different widths w1 and w2 and/or different angles ε1 and ε2 such that a light wave polarized initially parallel to the base sides (111, 121) of the converter elements (11, 12), after passing through the first and of the second converter element (11, 12), is polarized perpendicular to the base sides (111, 121) of the converter elements. The invention also relates to a polarization converter and to a polarization converter element.

摘要： In the examples provided herein, a system includes a loop waveguide; and a grating coupler formed on the loop waveguide to couple light impinging on the grating coupler having a first polarization into the loop waveguide in a first direction, and to couple light having a second polarization, orthogonal to the first polarization, into the loop waveguide in a second direction. The system also includes a ring resonator positioned near the loop waveguide tuned to have a resonant wavelength at a first wavelength to couple light at the first wavelength out of the loop waveguide into the ring resonator. An output waveguide positioned near the ring resonator couples light out of the ring resonator into the output waveguide; and a photodetector detects light propagating out of a first end and a second end of the output waveguide.
