摘要:
An optical biosensor including a bio-sensing unit configured to receive an optical signal and generating a sensed optical signal, the wavelength of which varies according to a result of sensing a biomaterial; and a spectrometer including a plurality of ring resonators for dividing the sensed optical signal according to a wavelength and generating a plurality of output optical signals, respectively.
摘要:
A light-coupling structure in a type of heat-assisted magnetic recording is provided, the structure not needing a separate additional slider or a suspension arm through reduction in variation amounts of coupling due to vibrations, and being realized as a high efficient, low-cost structure with compact size. The light-coupling structure in a type of heat-assisted magnetic recording (HAMR) includes: a waveguide having, at its one end, a mirror part inclined at a certain angle; a slider having one of a groove provided along a width direction of one side thereof contacting the waveguide and a via hole provided along a width direction of one side thereof contacting the waveguide; and a fiber butt-connected to the waveguide by means of a connector provided parallel with the slider.
