One-Wave Optical Phase Conjugation Mirror by Actively Coupling Arbitrary Light Fields into a Single-Mode Reflector
'American Physical Society (APS)', 2015Co-Authors: Lee Kyeoreh, Lee Junsung, Park Jung-hoon, Ji-ho Park, Park YongkeunAbstract:Rewinding the arrow of time via phase conjugation is an intriguing phenomenon made possible by the Wave Property of light. Here, we demonstrate the realization of a one-Wave optical phase conjugation mirror using a spatial light modulator. An adaptable single-mode filter is created, and a phase-conjugate beam is then prepared by reverse propagation through this filter. Our method is simple, alignment free, and fast while allowing high power throughput in the time-reversed Wave, which has not been simultaneously demonstrated before. Using our method, we demonstrate high throughput full-field light delivery through highly scattering biological tissue and multimode fibers, even for quantum dot fluorescence.clos

One-Wave optical phase conjugation mirror by actively coupling arbitrary light fields into a single-mode reflector
'American Physical Society (APS)', 2015Co-Authors: Lee Kyeoreh, Lee Junsung, Park Jung-hoon, Ji-ho Park, Park YongkeunAbstract:Rewinding the arrow of time via phase conjugation is an intriguing phenomena made possible by the Wave Property of light. To exploit this phenomenon, diverse research fields have pursed the realization of an ideal phase conjugation mirror, but an optical system that requires a single-input and a single-output beam, like natural conventional mirrors has never been demonstrated. Here, we demonstrate the realization of a one-Wave optical phase conjugation mirror using a spatial light modulator. An adaptable single-mode filter is created, and a phase-conjugate beam is then prepared by reverse propagation through this filter.

polarization independent metamaterial analog of electromagnetically induced transparency for a refractive index based sensor
IEEE Transactions on Microwave Theory and Techniques, 2012Co-Authors: Fanyi Meng, Daniel Erni, Jongchul LeeAbstract:A polarization-independent metamaterial analog of electromagnetically induced transparency (EIT) at microWave frequencies for normal incidence and linearly polarized Waves is experimentally and numerically demonstrated. The metamaterial consists of coupled “bright” split-ring resonators (SRRs) and “dark” spiral resonators (SRs) with virtually equal resonance frequencies. Normally incident plane Waves with linear polarization strongly couple to the SRR, but are weakly interacting with the SR, regardless of the polarization state. A sharp transmission peak (i.e., the transparency window) with narrow spectral width and slow Wave Property is observed for the metamaterial at the resonant frequency of both, the bright SRR and the dark SR. The influence of the coupling strength between the SRR and SR on the frequency, width, magnitude, and quality factor of the metamaterial's transparency window is theoretically predicted by a two-particle model, and numerically validated using full-Wave electromagnetic simulation. In addition, it is numerically demonstrated that the EIT-like metamaterial can be employed as a refractive-index-based sensor with a sensitivity of 77.25 mm/RIU, which means that the resonance Wavelength of the sensor shifts 77.25 mm per unit change of refractive index of the surrounding medium.
