3. 68‐1: Invited Paper:A Waveguide‐type Retinal Scan AR Display with Pupil Expansion System

Author

Yoshikaie, Akira, Ohki, Kenji, Ogawa, Yusuke, Funakiri, Atsushi, Seno, Katsunori, Abe, Kuniya, Ando, Masahiro, Nakano, Satoshi, and Ogawa, Ryo

Abstract

We have developed a full‐color retinal scan AR display presenting a focus‐free image with a novel pupil switching system featuring a holographic lens array on multiple waveguide optics. The display demonstrated a stereoscopic image with 50° diagonal field of view and 5.0‐mm eyebox.

7. 17‐3: Distinguished Paper:A Plastic Holographic Waveguide Combiner for Light‐weight and Highly‐transparent Augmented Reality Glasses

Author

Yoshida, Takuji, Tokuyama, Kazutatsu, Takai, Yuichi, Tsukuda, Daisuke, Kaneko, Tsuyoshi, Suzuki, Nobuhiro, Anzai, Takafumi, Yoshikaie, Akira, Akutsu, Katsuyuki, and Machida, Akio

Abstract

We have developed a unique production process of a full‐color plastic holographic waveguide combiner with a light‐weight and see‐through capability. The novel plastic waveguide technology enables us to increase design flexibility in the eyewear and to expand the market for augmented reality (AR). This paper presents the approach to production.

11. Signatures of Γ1-Γ5 mixed-mode polaritons in polarized reflectance spectra of ZnO.

Abstract

Theoretical and experimental studies were carried out on exciton-polaritons excited in ZnO. Polaritons in which both Γ(1) and Γ(5) excitons couple to electromagnetic waves simultaneously are shown to exist, and their signatures are observed in polarized reflectance spectra measured under k is perpendicular to a and E is parallel to c configurations for an m-plane sample. Theoretical calculations reveal that the mixed-mode polaritons consist of one Γ(1) transverse mode and two Γ(5) longitudinal modes. It is also shown that the signatures are sensitive to the valence band ordering.
