ABSTRACTThe third-order nonlinear optical properties of a series of homopolymers and a random copolymer of conjugated aromatic Schiff base polymers have been investigated by picosecond third harmonic generation spectroscopy in the wavelength range 0.9–2.4 um. The off-resonant χ(3)(-3ω;ω, ω, ω) value at 2.4 μm was found to be 1.6×10−12esu for the parent polymer (PPI). 2, 5-Dimethoxy and 2, 5-dihydroxy substitutions or random colpolymerization was found to enhance the nonresonant optical nonlinearity of PPI by a factor of 1.5–4.5. 2-Methyl substitution lowered the χ(3) value. The three-photon resonance enhanced χ(3) of the polymers was in the range l.l×10−11 to 5.2×l0−11 esu. A three-level essential states model was found to describe the observed χ(3) spectra and the resulting fitting parameters were used to explain the observed trends in structure - χ(3) relationships.

AbstractTopological insulators (TIs) possess exciting nonlinear optical properties due to presence of metallic surface states with the Dirac fermions and are predicted as a promising material for broadspectral phodotection ranging from UV (ultraviolet) to deep IR (infrared) or terahertz range. The recent experimental reports demonstrating nonlinear optical properties are mostly carried out on non-flexible substrates and there is a huge demand for the fabrication of high performing flexible optoelectronic devices using new exotic materials due to their potential applications in wearable devices, communications, sensors, imaging etc. Here first time we integrate the thin films of TIs (Bi2Te3) with the flexible PET (polyethylene terephthalate) substrate and report the strong light absorption properties in these devices. Owing to small band gap material, evolving bulk and gapless surface state conduction, we observe high responsivity and detectivity at NIR (near infrared) wavelengths (39 A/W, 6.1 × 108 Jones for 1064 nm and 58 A/W, 6.1 × 108 Jones for 1550 nm). TIs based flexible devices show that photocurrent is linearly dependent on the incident laser power and applied bias voltage. Devices also show very fast response and decay times. Thus we believe that the superior optoelectronic properties reported here pave the way for making TIs based flexible optoelectronic devices.

The Way

New acidochromic and photochromic compounds with nonlinear optical properties have been designed and synthesized. The hyperpolarizabilities of the zwitterionic colored forms have been quantified with polarized hyper-Rayleigh scattering experiments. The static value of oxazolidino-indoline 2 is found to be as high as Disperse Red One. This opens the way to novel multi-addressable NLO-systems.
