We fabricate and investigate wavelength selective components utilizing channel plasmon polaritons (CPPs) and operate at telecom wavelengths: a waveguide-ring resonator-based add-drop multiplexer (WRR-ADM) and a compact (3.75-microm-long) Bragg grating filter (BGF). The CPP waveguides represent 0.5-microm-wide and 1.3-microm-deep V-grooves in gold, which are combined with a 5-microm-radius ring ...

High sensitivity to fabrication errors is a main challenge in using high-Q resonators. Here we show that by carefully choosing the optical tuning using an evolutionary algorithm, a drastically distorted transmission function can be restored. High Q ring resonators have been shown to enable novel functionalities on chip[1,2], however the main challenge in using high Q resonators is their high se...

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...

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...

A fiber guide array resonator is proposed and shown to obey a nonlinear Schrödinger model in a square well potential with nonlinearity defocusing inside the well and focusing outside. This model is proved to possess nonlinear states which are i) continuous extensions of the linear eigenstates, ii) remarkably stable up to a threshold amplitude, iii) unstable at the threshold where nonlinear tunn...
