“…And silicon-based photonic devices also have complementary metal oxide semiconductor (CMOS) process compatible, small size, communication band transparent, anti-radiation and so on. It is precisely because of large bandwidth, low latency, low power consumption, low crosstalk and other advantages [13][14][15][16][17][18][19][20][21]. Emerging information technologies such as optical communications, optical interconnects and optical sensing based on the integration of silicon photonics demonstrate the development trend of building new information hardware.…”

The silicon photon technology platform is low transmission loss, small size, low cost of the process and easy integration with electronic components and other characteristics. It is designed to design high-density optical communication network system has a considerable advantage. Such as high-density wavelength division multiplexing (DWDM) system, that is through the different wavelengths of signal processing. So that it can be used for optical connection switches, routing and other applications. It composed of a DWDM system, through the Mach-Zehnder interferometer, ring resonator (Add/Drop), array waveguide grating (AWG) and grating coupler and other structural components. It is designed by components to filter, switch, adjust and detect functions. The characteristics of the ring resonator are for wavelength selection. It is suitable for the design of optical switches, signal switching and modulation applications. It is also the focus of this lab and this chapter to explore and study. The general edge coupling, between the optical fiber and the waveguide dimension is very different. As a result, larger insertion loss is caused. This study uses the vertical coupling method to investigate the characteristics of a ring resonator.

“…The ideal resonator for wavelength division multiplexing (WDM) system has a wide free spectral range (FSR) and high finesse to accommodate many channels, high transmission at resonance to minimize insertion loss, and a large extinction ratio to minimize crosstalk. Ring resonators based on waveguide structures with weak lateral confinement have very low propagation loss [2][3][4] . However, the small refractive index contrast of the weakly guiding structures leads to high radiative bending losses at ring/disk diameters below 1 mm.…”

In recently years, high-index-contrast semiconductor ring and disk resonators have attracted much attention.Nanofabrication techniques now allow the realization of semiconductor microcavity ring and disk resonators with evanescent wave coupling to submicron-width waveguides across submicron-width air gaps. In this paper, we use the finite-difference time-domain (FDTD) method to simulate the coupling efficiencies and resonant frequencies for optical microcavity ring and disk resonators devices. Studies of the transmission characteristics illustrate the transition from single-mode resonances to whispering-gallery-mode resonances as the waveguide width of the micro-ring approaching to a fulfilled micro-disk.

“…Previous integrated waveguide-type ring-geometry resonator devices are typically large cavity structures ( 1 mm radius) based on weakly guiding waveguides [1]- [7]. Weakly guiding single-ring resonators have been used for propagation loss measurements in low-loss silica-based waveguides [1]- [6] and in polymer waveguides [7]. The weakly guiding ring resonators are created by a very small difference (e.g., ) between the index of refraction of the core and cladding.…”

We report the measurement of cavity propagation losses in nearly single-mode semiconductor waveguide-coupled ring and disk microcavity optical resonators. Using a novel 10.5-m-diameter ring resonator, we measure transverse electric (TE) and transverse magnetic (TM) field intensity losses in 0.35-m-wide ring waveguide cavities in the 1.55-m-wavelength region. We present the experimental results for nanofabricated AlGaAs/GaAs 10.5-m-diameter ring and disk resonators to quantify cavity losses and to show the feasibility of these promising and robust submicron-scale devices.
