    Silicon Photonic Technology Drives Optical Ultrasound Detector

    Article obtained from Photonics RSS Feed.

    A base of miniaturized photonic circuits, undetectable to the human eye and assembled on top of a silicon chip, has enabled a German research team to develop an ultrasound detector they say is the smallest in existence. The detector is 100× smaller than a human hair (about 0.5 µm) and achieves superresolution imaging at a previously unattainable level.

    Known as the silicon waveguide-etalon detector (SWED), the detector monitors changes in light intensity propagating through the minitiaruized photonic circuits instead of recording voltage from piezoelectric crystals. Since its development in the 1950s, core ultrasound detection technology has been heavily reliant on piezoelectric detectors, which convert ultrasound wave…
