In this paper we propose a set of novel tunable optical power splitters based on active microring resonators. They work by operating ring resonators in the transient zone between full resonance and off-resonance states for a specific wavelength. We can achieve different split ratios by either varying the bias voltage, or by selectively enabling a given resonator with a specific split ratio amon...

In the present study, we provide a detailed analysis for the study of photonic metamaterials. We demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and visible band. We provided optical measurements only for one case, in which electric component of the incident field was coupled to planar split ring resonator array. We consecuti...

In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

In this paper, a high-Q resonator is presented and its structure is in the shape of spiral, hence Complementary Spiral Resonator. The measurement of the complementary spiral resonator itself shows that a higher loaded quality factor is provided as compared to the Double H-Shaped Resonator. The resonator was designed to operate at a frequency of 10 GHz and the phase noise performance of the syst...

Electro-optic modulators lie at the heart of complex integration and high-density electro-optic systems. One representative is thin-film lithium niobate-based microring modulator which has demonstrated advantages compact footprint, low optical loss, high modulation efficiency. However, linewidth extinction ratio ring are fundamentally limited by losses coupling, respectively. To this end, a nov...
