ABSTRACT:
An optical biosensor using a surface plasmon resonance phenomenon includes an input optical waveguide including a first optical mode converting unit for converting a core mode to a cladding mode; and an optical sensing unit for allowing a specific wavelength among wavelengths constituting the converted cladding mode to be lost according to density of bio-material. The optical biosensor can accurately measure density of bio-material by using an optical signal.
