“…Exploiting optical rectification, as well as the electro-optic effect, permits generation and detection of terahertz radiation. − Such capability permits the utilization of terahertz frequencies for spectroscopic and sensing applications. Terahertz radiation is absorbed by the phonon modes of many organic crystals such as plastic explosive materials (RDX, HMX), and thus terahertz spectroscopy is relevant to security screening as well as general spectroscopic applications.…”

“…It is not easy to make a compact LiNbO 3 switch array because of the electrical crosstalk in high-speed operations. On the other hand, electro-optic (EO) polymer switches and modulators have desirable features for arrayed-type devices [5][6][7]. They can be easily fabricated by a spincoating process; therefore, it is easy to integrate lots of EO polymer modulators on the same substrate to form a mutichannel arrayed modulator.…”

A 16-arrayed polymeric optical modulator is fabricated using an electro-optic (EO) polymer with a large EO coefficient and good thermal stability. The 16-arrayed modulator has lumped type electrodes with a response time of less than one nanosecond. The 16-arrayed modulator has good uniform modulation characteristics between the individual modulators. The deviation of half-wave voltages is 0.2 V and that of insertion losses about 1 dB. Crosstalks range from -28 to -36dB and extinction ratios are more than 21 dB.

Organic second-order nonlinear optical (NLO) chromophores are the main constituent part of nonlinear optical material. Scientists are dedicated to researching on the synthesis of novel chromophores with excellent performance by the facile design and modification of organic second-order NLO chromophores for decades. However, the researches on NLO chromophores in order to achieve the efficient translation of molecular microscopic nonlinearity (hyperpolarizability β) into macroscopic electro-optic (EO) coefficients r 33 is still a challenging task. In recent years, a large number of essays report the novel NLO chromophores by adding isolation groups which can change the shape of chromophores and decrease the electrostatic interaction aimed to achieve the bigger EO coefficients. In this review, the recent processes of novel NLO chromophores modified by isolation groups are reviewed systematically and comprehensively.
