Abstract
Example embodiments relate to alignment-tolerant photonic sensing systems. An example sensing system includes an illumination module for delivery of a light beam. The sensing system also includes a cartridge that includes a photonic sensor chip having a length axis and a width axis. The photonic sensor chip includes a plurality of grating couplers in a first areal portion of the photonic sensor chip. The photonic sensor chip also includes a plurality of sensing sites. Additionally, the photonic sensor chip includes waveguides connecting each grating coupler to a respective sensing site or group of sensing sites of the plurality of sensing sites. Further, the sensing system includes a cartridge holder for releasably receiving and locking the cartridge into a sensing position. The photonic sensor chip is aligned relative to the illumination module up to permitted alignment tolerances when the cartridge is locked into the sensing position.
