“…Numerical comparisons with a full wave commercial software successfully validate the proposed design procedure. Lens antennas are widely used in millimeter wave applications such as automotive radar [1,2], satellite transmissions [3], or indoor communications [4]. Lens antennas typically consist of a dielectric lens (spherical or hemispherical) fed by a primary source (single feed or array).…”

“…Arrayed waveguide gratings (AWGs) are key devices in optical communication systems in which they can serve as multiplexers [1][2][3][4][5], the spectral response of AWG plays an important role in dense wavelength-division multiplexing (DWDM) system. Some factors will result in the shift of the transmission spectrum of the AWG device, such as manufacturing tolerances, temperature, etc.…”

“…Lanthanum-doped lead zirconate titanate, (Pb, La)(Zr, Ti)O 3 (PLZT), is an attractive material of large electro-optic coefficient and high-speed response (<1 ns), which has been widely used in the design and fabrication of optoelectronic devices, including 1×2 Y-branch switches [23,24], MZI/ MZ-type switches and modulators [25,26], tunable arrayed waveguide gratings (AWGs) [27], and so on. The EO coefficients of most PLZT thin films are larger than the other ferroelectric oxide films, involving LiNbO 3 (LN) films (3∼31 pm/ V) [28] and BaTiO 3 films (∼23 pm/V) [29], though they are usually much smaller than those of PLZT ceramics [30,31], which are within the range of 30∼100 pm/V.…”

Waveguide ring resonators (WRRs) operating at a telecom window of 1.4∼1.6 μm based on asymmetric Au-(Pb, La)(Zr, Ti)O 3 -Au structure is proposed and investigated. Electro-optical control of such WRRs is conducted by introducing epitaxial (Pb, La)(Zr, Ti)O 3 (PLZT) thin films as the core layer deposited between the upper and lower gold slabs with different widths. The long-term reliability, large electrooptic (EO) coefficients, and spontaneous polarization properties of PLZT thin films have ensured high performance of our WRRs. It has been demonstrated that the footprint of WRR can be fabricated less than 20 μm 2 with the radius of ring resonator around 1 μm through combining PLZT thin films with surface plasmons (SPs). Furthermore, the large extinction ratio (∼43 dB), as well as comparatively low insertion loss (<10.5 dB), and moderate modulation sensitivity (0.8 nm/V) can be achieved with proposed WRRs in the wavelength range of 1.4∼1.6 μm. Besides, the strong mode confinement capacity of such asymmetric metal-insulator-metal (MIM) structure can support high bending waveguides, paving the way for the fabrication of more compact electro-optic WRRs with nanometer-scale radius that can work in the other wavelength ranges.

“…Arrayed waveguide gratings (AWG) can serve some basic functions including multiplexing, demultiplexing, interconnection, and so on, the spectral response of AWG plays an important role in dense wavelength‐division multiplexing system . The conventional AWG device usually possesses a Gaussian spectral response, which imposes a strong wavelength control in the communication network.…”

In this article, the RIE process has been improved, a 17317 polymer arrayed waveguide grating (AWG) multiplexer with flat spectral response have been designed and fabricated using FPE polymer materials. Using the steam-redissolution technique, the insertion loss and the crosstalk have been reduced. Experimental results show that the central wavelength is 1550.86 nm, and 3-dB bandwidth is about 0.478 nm, insertion loss is 10.5 dB, crosstalk is about 220.5 dB. The insertion loss of an AWG device is reduced by about 3 dB for the central channel and 4.5 dB for the edge channels, and the crosstalk is reduced by 1.5 dB after the steam-redissolution.
