DUAL COUPLER DEVICE, SPECTROMETER INCLUDING THE DUAL COUPLER DEVICE, AND NON-INVASIVE BIOMETRIC SENSOR INCLUDING THE SPECTROMETER |
摘要 |
Provided are a dual coupler device configured to receive lights of different polarization components, a spectrometer including the dual coupler device, and a non-invasive biometric sensor including the spectrometer. The dual coupler device may include, for example, a first coupler layer configured to receive a light of a first polarization component among incident lights. and a second coupler layer configured to receive a light of a second polarization component among the incident lights, wherein a polarization direction of the light of the first polarization component is perpendicular to a polarization direction of the light of the second polarization component. The first coupler layer and the second coupler layer may be spaced apart from each other and extended along a direction in which the light propagates in the first coupler layer and the second coupler layer. |
