    Abstract: Example embodiments relate to detectors for detecting electromagnetic radiation. One embodiment includes a detector for detecting electromagnetic radiation spanning a range from a first wavelength to a second wavelength. The detector includes an array of funnel elements for propagating electromagnetic radiation from a second plane towards a first plane. Each of the funnel elements includes an entrance end and an exit end. The entrance ends of the array of funnel elements define the second plane. The entrance end is larger than half of the second wavelength in a medium from which the electromagnetic radiation enters the detector. The exit end is smaller than half of the first wavelength of in the medium. The detector also includes an array of photosensitive elements for detecting electromagnetic radiation incident on the array of photosensitive elements. Each funnel element is associated with a photosensitive element. The array of photosensitive elements defines the first plane.

    Abstract: The present disclosure relates to a photonic chip comprising a first optical propagation element and an optical resonator for optically coupling the first optical propagation element to a second optical propagation element. The second optical propagation element may be external the photonic chip or a part of the photonic chip. The first optical propagation element comprises a first material with a first refractive index that is higher than a second refractive index of a second material of the second optical propagation element. An optical coupling efficiency of above 99% can be achieved.
