Integrated microlenses and multimode interference devices for microflow cytometers
… simulated. An alternative device, the multimode interference device (MMI), which makes use of the self-imaging phenomenon in multimode waveguides, was also studied due to its less stringent fabrication tolerances. Optical components including channel waveguides, to route light on chip, …
