1. An optical transmitter comprising:
a light source, implemented on a chip, to generate light that is transmitted out of the optical transmitter;
a waveguide, implemented on the chip, to receive the light from the light source and transmit the light along a transmission direction of the waveguide, the waveguide further to receive, via an off-chip optical fiber, additional light from an off-chip light source such that the additional light propagates within the waveguide against the transmission direction of the waveguide; and
a light detector, implemented on the chip, to measure the additional light from the waveguide to align the optical fiber with the waveguide based on the additional light that is received by the light detector.
