Light Transmission through Three Types of Translucent Zirconia
Objective: Zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic. Methods: In this in vitro study, Disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely Mamut, Heany and ZirkonZahn (n=5). A disc-shaped specimen (11.5 mm in d...
متن کاملLight transmission through a subwavelength slit: waveguiding and optical vortices.
The anomalous (i.e., more than 100%) light transmission through a subwavelength slit in a thin metal plate is accompanied by a combination of waveguiding and phase singularities of the field of power flow near the slit. The crucial role of these phase singularities (such as optical vortices and saddle points) in exciting the waveguide modes is systematically studied. We predict transmission eff...
متن کاملUltraefficient control of light transmission through photonic potential barrier modulation.
An optical modulation mechanism based on dynamically shifting the photonic potential barrier of a photonic crystal waveguide is presented. The modulation mechanism is modeled by the one-dimensional quantum tunneling effect using the Schrödinger equation. The calculation results show that the modulation efficiency is 200 times higher than that of the conventional Mach-Zehnder modulator. Based on...
