Abstract
Commercial silicon photonic (SiP) biosensor architectures rely on expensive swept-tunable lasers that limit their use for widespread, point-of-care applications. An alternative is the use of fixed wavelength lasers integrated directly on a silicon photonic platform. This study investigates the design considerations of such architectures.
