“…Evidently, the fabricated devices still suffer from too high insertion loss to meet practical applications. In comparison with the other low power VOAs [ 39 , 40 , 41 ], the power consumption is a little larger as well. It is mainly due to the thick polymer cladding that extends the distance of thermal diffusion.…”

A flexible thermo-optic variable attenuator based on long-range surface plasmon-polariton (LRSPP) waveguide for microwave photonic application was investigated. Low-loss polymer materials and high-quality silver strip were served as cladding layers and core layer of the LRSPP waveguide, respectively. By using finite element method (FEM), the thermal distribution and the optical field distribution have been carefully optimized. The fabricated device was characterized by end-fire excitation with a 1550 nm laser. The transmission performance of high-speed data and microwave modulated optical signal was measured while using a broadband microwave photonics link. The results indicated that the propagation loss of the LRSPP waveguide was about 1.92 dB/cm. The maximum attenuation of optical signal was about 28 dB at a driving voltage of 4.17 V, and the variable attenuation of microwave signals was obviously observed by applying different driving voltage to the heater. This flexible plasmonic variable attenuator is promising for chip-scale interconnection in high-density photonic integrated circuits and data transmission and amplitude control in microwave photonic systems.

“…The resonant wavelength could be tuned by applying electric power to the heater on the ring waveguide. As shown in Figure 7a, owing to the positive thermo-optic coefficient of SiO2 [28], a red shift could be observed. The blue circles mark the resonance peak under the same order.…”

A high-Q-factor tunable silica-based microring resonator (MRR) is demonstrated. To meet the critical-coupling condition, a Mach–Zehnder interferometer (MZI) as the tunable coupler was integrated with a racetrack resonator. Then, 40 mW electronic power was applied on the microheater on the arm of MZI, and a maximal notch depth of about 13.84 dB and a loaded Q factor of 4.47 × 106 were obtained. The proposed MRR shows great potential in practical application for optical communications and integrated optics.

“…As the centerpiece of wavelength division multiplexing (WDM), AWG has been fabricated by silicon-on-insulator [5], SiO 2 [6,7], and polymers [8][9][10][11]. Though AWG has been highly developed by the standard industry technology of planar lightwave circuits (PLCs), and the cost is being gradually reduced by the mature fabrication process of silica-based waveguide [12][13][14], the polymer AWG has its own advantages and can avoid complex preparation processes such as thermal oxidation, plasma-enhanced chemical vapor deposition (PECVD), and inductively coupled plasma (ICP) etching [12][13][14]. Compared with silica-based devices, polymer-based devices can skip several steps in manufacture, resulting in reduced prices for the setup and, especially for small batch sizes, a reduced price per unit [15][16][17].…”

A 5-channel polymer/silica hybrid arrayed waveguide grating (AWG), fabricated through a simple and low-cost microfabrication process is proposed, which covers the entire O-band (1260–1360 nm) of the optical communication wavelength system. According to the simulation results, the insertion loss is lower than 4.7 dB and the crosstalk within 3-dB bandwidth is lower than ~−28 dB. The actual fiber–fiber insertion loss is lower than 14.0 dB, and the crosstalk of the 5 channels is less than −13.0 dB. The demonstrated AWG is ideally suitable for optical communications, but also has potential in the multi-channel sensors.
