    This paper presents the use of a micro-optical conjugate mirror for 3D pixel construction, which can be used to construct and reconstruct the 3D pixel using the microoptical device. A conjugate mirror is formed by a semiconductor device, which is a tiny nonlinear optical device. By using the common laser as the input light beam, the object and reference beams can be formed by the reflected light beams from the PANDA ring through and drop ports. The interference between these two beams forms the 3D pixel by the four-wave mixing behavior coupled by the two nonlinear side rings. The 3D pixel is seen in the form of whispering gallery modes (WGMs) at the PANDA ring center, which is the real image, while the reconstruction images can also be obtained via the PANDA ring output port. The simulated results and graphic designs are obtained by using Optiwave program. This is useful for real 3D image display applications.

    Psychiatric investigation using WGMs in microring circuits

    The use of an electrical probe is formed by whispering gallery modes (WGMs) of light within the coated microring circuits, in which the electrical signal is generated by trapped electron tunneling along the circular path of the coated microring circuit. The collection of electrons is formed within the WGMs, where in this study, a modified nonlinear microring resonator known as a PANDA ring resonator is coated by gold material and forms the mirroring circuit. The induced current (magnetic field) within the circuit occurs by the coupling effects between trapped electrons and coated ring, which can penetrate into the brain cells and transform to the required signals via the terahertz carrier for psychiatric investigations. The use of WGMs for 3D image construction using a PANDA conjugate mirror is also discussed, which is useful for thermal and imaging sensors. © The Authors.
