1. A subsystem, comprising:
a receptacle for an optical fiber;
a photonic integrated circuit including a waveguide, the photonic integrated circuit transmitting in the optical fiber an
optical signal of a first wavelength and receiving from the optical fiber an optical signal of a second wavelength; and
a standalone photodiode, wherein the standalone photodiode and the photonic integrated circuit are encapsulated inside an
optical module such that the photodiode is positioned adjacent to one end of the photonic integrated circuit at an angle relative
to a direction of light transmission in the waveguide to receive from the waveguide the optical signal of the second wavelength.
