“…A comprehensive review of the sensing applications of nanobeam cavities was provided by Qiao et al [19]. There are also many other types of photonic/plasmonic crystals cavities for biochemical sensing, for example, tuberculosis detection based on the photonic bandgap with the blood sample as the defect layer [20], 2-D photonic crystal cavity for cancerous cell detection [21], cancer biomarker detection and drug diagnostics using 2-D silicon PTC microcavities coupled with waveguides in the telecom wavelength band [22], resonance recognition for an artificial organic substance by using 2-D hybrid photonic-plasmonic crystal cavities [23], glucose sensing by placing a dielectric nanowire on the metal grating with a nano-trench cavity [24], and protein detection by using gold gratings deposited on silicon substrate with a graphene-laced cavity [25]. Most of the afore-mentioned works detected biochemicals based solely on the resonance shift, a result due to the variation in the refractive index (RI), which may post a selectivity problem because it is quite common that different biochemicals may have a nearly identical RI value.…”

In this study, we propose a biochemical sensor that features a photonic cavity integrated with graphene. The tunable hybrid plasmonic-photonic sensor can detect the molecular fingerprints of biochemicals with a small sample volume. The stacking sequence of the device is “ITO grating/graphene/TiO2/Au/Si substrate”, which composes a photonic band gap structure. A defect is created within the ITO gratings to form a resonant cavity. The plasmonic-photonic energy can be confined in the cavity to enhance the interaction between light and the analyte deposited in the cavity. The finite element simulation results indicated that the current sensor exhibits very high values in resonance shift and sensitivity. Moreover, the resonance spectrum with a broad resonance linewidth can identify the molecular vibration bands, which was exemplified by the fingerprint detections of protein and the chemical compound CBP. The sensor possesses an electrical tunability by including a graphene layer, which allowed us to tune the effective refractive index of the cavity to increase the sensor’s sensing performance. In addition, our device admits a phononic bandgap as well, which was exploited to sense the mechanical properties of two particular dried proteins based on the simplified elastic material model instead of using the more realistic viscoelastic model. The dual examinations of the optical and mechanical properties of analytes from a phoxonic sensor can improve the selectivity in analyte detections.

Overcoming the optical diffraction limit and reducing the size of optoelectronic integrated circuits have become requirements for the rapidly increasing demand for data transmission and novel functionality. These goals can be achieved by applying a surface plasmon mode that can attain subwavelength confinement. In this Tutorial, we discuss the operation principle and development of the surface plasmon amplification of the stimulated emission of radiation and the newly developed plasmonic nanolasers that play essential roles in reducing system sizes. Nanowire-type surface plasmon polariton (SPP) nanolasers with semiconductor–insulator–metal structures were developed and integrated with graphene, which offers numerous advantages to SPP nanolasers. Furthermore, the electrical modulation mechanism of nanolasers on graphene–insulator–metal (GIM) platform was also verified, which can recognize integrated SPP detectors. Therefore, we propose using an integrated plasmonic circuit on the GIM platform to provide multiple functionalities in a compact footprint.
