Abstract: A photonic system and a method for analysing target molecules that emit radiation upon being exposed to excitation radiation includes a radiation source configured to provide excitation radiation with a predetermined polarization state, and a photonics chip that includes an analysis region for exposing target molecules to radiation from the radiation source, so that target molecules with a dipole component along the direction of polarization of the excitation radiation emit radiation with an angular profile. A waveguide structure captures radiation emitted from the analysis region by target molecules. The waveguide structure is configured to extract the emitted radiation in different positions in accordance with the angular profile of the emitted radiation for sampling the angular profile.

Abstract: A resonator structure is disclosed. In some embodiments, the resonator structure may include a metal-insulator-metal waveguide comprising a first metal layer, a second metal layer, and an insulating layer between the first metal layer and the second metal layer, wherein the insulating layer comprises a resonating cavity. The resonator structure may further include a mirror formed in the resonating cavity, wherein the mirror comprises at least one nanoscale metallic reflector positioned at least partly in the insulating layer.

Abstract: A waveguide integrated photodetector (100) is described. The waveguide integrated photodetector comprises a first layer (110) of plasmon supporting material whereby the first layer (110) has an input slit (112) extending through the first layer (110) for coupling first radiation to the waveguide. The photodetector (100) also comprises a second layer (120) of plasmon supporting material facing the first layer and separated from the first layer by a first distance in a first direction. The second layer (120) has an output slit (122) extending through the second layer (120) and separated from the input slit (112) by a second distance extending along a second direction differing from first direction. The photodetector system (100) also comprises a dielectric layer (130) interposed between the first layer (110) and the second layer (120), and a detector (140) near the output slit (122) for detecting the radiation coupled out through the output slit (122).
