The add drop filter (ADF) is one of the most significant devices for coarse wavelength
division multiplexing (CWDM) systems to add and/or drop a required channel individually …

A new optical channel drop filters (CDFs) configuration based on photonic crystals ring
resonators (PCRRs) is provided. The transmission characteristics for single-ring and …

We investigated the characteristics of photonic crystals (PCs) nano-ring resonators as
biochemical sensors theoretically. The new nano-ring resonators were formed by removing …

We fabricated and theoretically investigated an add–drop filter (ADF) using an on-chip
whispering gallery mode (WGM) microtoroid resonator with ultrahigh-quality factor (Q) side …

In this study, a photonic crystal ring resonator with a triangular lattice is used to design an
optical filter. The proposed structure is able to filter the central wavelength of 1548 nm with a …

In this paper, a new design of channel drop filters (CDFs) based on photonic crystals ring
resonators (PCRRs) is presented. The filter characteristics for single-ring and dual-ring …

Microcantilever sensors have been known as a fundamental design used in force sensors,
strain sensors and biochemical sensors. The fast-growing applications in …

An add-drop filter (ADF) fabricated using a whispering gallery mode resonator has different
crosstalks for add and drop functions due to non-zero intrinsic losses of the resonator. Here …

A design for enhancing the quality (Q) factor of a photonic crystal ring resonator (PCRR) is
introduced. The highest Q factor based on simulations is 121,000. The analysis of …

In this paper, we present a diamond-shaped biosensor based on the nano-ring resonator
using two-dimensional photonic crystal (2D-PhC). The biosensor is consisted of a ring …
