We present the THz transmission characteristics of a guided-mode resonance (GMR) notch filter made of alldielectric material. When the polarization angle for the ideal 1-D GMR filter changes from 0° to 180°, thetransmittance variation changes from 0 to 1 as a function of cos2 (Φ), where Φ is polarization angle.
However, if the second filter is installed at a rotation angle between 0° and 90° compared to the first filter,then the transmittance ranges for the polarization angles change from 0 to any value less than 1.

[Presentation Style] Onsite*Kentaro Nagamatsu1 （1. Tokushima Univ. (Japan)）[Presentation Style] Onsite
Virus inactivation technology is attracting much attention to realize mitigation of the spread of COVID-19.
There are many approaches for virus inactivation. One of the effective methods well known is directly
damaging their RNAs by ultraviolet (UV) light emitting diodes (LED). However, the quantum efficiency in the
UV-LED is much lower than that of the visible LEDs. So, a large cooling system is required owing to maintain
irradiation because LED generates heat. In this report, the present situation of UV-LED characteristic such as
the wavelength, quantum efficiency, and lifetime in LED are shown. Moreover, the virus inactivation effect by
the UV-LED with including COVID-19 is explained. Finally, we introduce the recent study in UV-LEDs
becoming the common in virus inactivation.

We have demonstrated a blackbody micro-emitter using etching-precipitation graphene that requires notransfer process. Long-lifetime and bright emission are achieved by using a bow-tie-shaped graphene. Thisgraphene-based micro-emitter is expected to be applied to integrated photonics and optoelectronics.

Surface plasmon resonance (SPR) sensors take advantages of label-free, real-time and surface-sensitive
detection. The SPR technology is widely used for studying binding kinetics of various biomolecules. However,
the typical SPR only has an evanescent depth. In this work, we discover a new phenomenon in aluminum
capped nanoslit array which possesses two distant evanescent depths in a single Fano mode. This dual-mode
in a single resonance property makes the Fano resonance useful for some innovative biosensing applications,such as self-referencing SPR sensors which applied in measuring the bio-reaction.
