1. An integrated optical device, comprising:
a plurality of waveguide cores disposed in an array oriented perpendicular to a longitudinal direction, wherein each waveguide core of the plurality of waveguide cores is elongated in the longitudinal direction;
a plurality of diode signal contacts disposed in a first signal contact array, of a plurality of signal contact arrays, the first signal contact array oriented in a transverse direction that is perpendicular to the longitudinal direction, wherein a respective waveguide core of the plurality of waveguide cores separates each diode signal contact of the plurality of diode signal contacts;
a plurality of diode ground contacts disposed in a first ground contact array, of a plurality of ground contact arrays, the first ground contact array oriented in the transverse direction, wherein a respective waveguide core of the plurality of waveguide cores separates each diode ground contact of the plurality of diode ground contacts; and
a plurality of diodes disposed in an array perpendicular to the longitudinal direction, wherein at least two diodes of the plurality of diodes each having a structure that comprises:
a corresponding portion of a waveguide core of the plurality of waveguide cores;
a corresponding diode ground contact of the plurality of diode ground contacts; and
a corresponding diode signal contact of the plurality of diode signal contacts
wherein a first waveguide core of the plurality of waveguide cores is separated from a second waveguide core of the plurality of waveguide cores adjacent to the first waveguide core by a separation region, and the separation region includes a respective diode ground contact of two or more of the plurality of ground contact arrays and a respective diode signal contact of two or more of the plurality of signal contact arrays.
