| 摘要 |
<p>The present invention relates to a wavelength-tunable optical receiver structure using a liquid crystal wavelength-tunable filter. The wavelength-tunable optical receiver structure includes: the liquid crystal wavelength-tunable filter (600) which transmits extraordinary polarized light by selectively transmitting only desired wavelength from incident light, and reflects ordinary polarized light; a quarter wave plate (120) which converts the ordinary polarized light, reflected by the liquid crystal wavelength-tunable filter (600), into an extraordinary polarized light; a reflection mirror (130) which transmits an optical signal of which an element of polarized light is changed in the quarter wave plate (120) to the liquid crystal wavelength-tunable filter (600); and a photoelectric conversion unit (20) which converts the optical signal, input from the liquid crystal wavelength-tunable filter (600), into an electrical signal and then outputs the electrical signal.</p> |
