“…In the last decade, several on-chip devices have been demonstrated with periodically patterned waveguides [1][2][3][4] and resonators [5][6][7][8][9][10]. Here, we present a novel microring resonator structure patterned with periodic circular air holes on a silicon-on-insulator (SOI) platform [11].…”

We demonstrate a novel periodically patterned ring resonator evanescently coupled with a coupler waveguide (CWG) on a silicon-on-insulator platform. In order to optimize the coupling, we phase match the ring resonator and the CWG by tuning the width of the CWG. In the transmission spectra, we measure a high extinction ratio of more than 20 dB and achieve a group index of ~20 in the slow-light regime. Beating patterns in the calculated mode profiles suggest strong interference between degenerate modes. This device opens up the possibility of new applications in compact device integration in wavelength-division multiplexing system while reducing the in-band four-wave mixing cross talk.

“…The miniaturization of a laser can be traced back to the early age of the laser, when compact semiconductor structures were introduced. In particular, the introduction of semiconductors as the gain media in 1962, followed by a series of elaborately engineered structures from heterostructure, quantum well, vertical‐cavity surface‐emitting laser (VCSEL), microdisk, photonic crystal, quantum dot to nanowire (NW) have made great success in shrinking a laser from bulk scale to wavelength level using reduced cavity sizes . For example, to date, typical commercial edge‐emitting quantum well laser diodes have dimensions of several micrometers in width and hundreds of micrometers in length, and a single quantum dot can lase in a photonic crystal cavity with overall dimension of merely 0.7(λ/ n ) 3 , where λ is the vacuum wavelength and n the refractive index of the dielectric .…”

and techniques have been proposed and/ or developed. Here we focus on a newly emerging area-plasmonic nanolaser that pursuing extremely smaller cavity size in one or more dimensions, and consequently extreme lasing conditions, by using a plasmonic cavity with feature size possibly far below the diffraction limit of light.The miniaturization of a laser can be traced back to the early age of the laser, when compact semiconductor structures were introduced. In particular, the introduction of semiconductors as the gain media in 1962, [11,12] followed by a series of elaborately engineered structures from heterostructure, [13] quantum well, [14] vertical-cavity surface-emitting laser (VCSEL), [15,16] microdisk, [17][18][19] photonic crystal, [20][21][22] quantum dot [23,24] to nanowire (NW) [25][26][27] have made great success in shrinking a laser from bulk scale to wavelength level using reduced cavity sizes. [28] For example, to date, typical commercial edgeemitting quantum well laser diodes have dimensions of several micrometers in width and hundreds of micrometers in length, and a single quantum dot can lase in a photonic crystal cavity with overall dimension of merely 0.7(λ/n) 3 , where λ is the vacuum wavelength and n the refractive index of the dielectric. [29] With optimized geometry and material for cavity design, lower structural dimension is expected. However, in a dielectric cavity with limited refractive index n, the cavity size is intrinsically restricted by optical diffraction limit that sets an ultimate limit λ/2n for both cavity length and mode size in all three dimensions.An effective step to shrink a cavity beyond the diffraction limit is converting light into surface plasmon polaritons (SPPs) in nanostructuralized metals, which is a kind of collective oscillation of quasi free electrons on the interface of a metal and a dielectric. [30] While SPP is featured with ultrahigh optical confinement and ultrafast relaxation process as shown in Figure 1a, [31] it is inevitably accompanied by ultrahigh energy dissipation (i.e., Ohmic loss), leading to a mutual balance between the mode size and the optical loss in either a nanowaveguide or a nanocavity as shown in Figure 1b. [32] For example, the transverse mode area of SPP mode on an Ag nanowire with diameter of 100 nm can be as small as 0.01 µm 2 but also exhibits a propagation loss larger than 200 dB mm −1 . Despite of the high loss coefficient of plasmonic resonance at optical frequency, a properly designed nanoplasmonic cavity coupled with a gain medium is possible to lase with miniature cavity length.Owing to their ultrahigh optical confinement, plasmonic nanolasers with cavity sizes beyond the diffraction limit of light, are attracting increasing attention for pursuing extreme lasing conditions on nanoscale including ultracompact cavity mode, ultrafast lasing modulation, significantly enhanced light-matter interaction, and Purcell effect. In this review, the recent progress on plasmonic nanolasers from both theoretical and experimental aspects is intro...

A one-dimensional photonic crystal racetrack ring resonator coupling with an optimized bus waveguide on a silicon-on-insulator wafer is proposed and demonstrated. The nonuniform free spectral range is realized in the resonator. A maximum group index of 37.6 and a slowdown factor of 11.0 are obtained. The nonuniform free spectral range and large group index are attributed to the slow-light effect near the band edge of the one-dimensional photonic crystal. Three-dimensional finite-difference time-domain method is performed to simulate the resonator. The simulation results show good agreement with the experimental results. The photonic crystal racetrack ring resonator demonstrated here will be beneficial for channel drop filters, wavelength-division multiplexing, lasers, and other applications.
