Double and single side-band suppressed-carrier optical modulator implemented at 1320 nm using LiNbO3 crystals and bulk optics

چکیده
We perform double sideband and single sideband suppressed-carrier modulators using a MachZehnder interferometer in free space. Two bulk LiNbO3 crystals are used to modulate the optical beam at 1319 nm in both branches of the interferometer. We present experimental results of the optical spectrum using heterodyne measurement technique. These results show maximum carrier and sideband suppression of 24 dB and 12 dB respectively for 1 GHz modulation frequency.

Designing voltage tunable single and multi-channel optical filter with 1DDPC nano-structure
An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...

متن کاملPhotoexcited Carrier Lifetime and Refractive Nonlinearity in Direct and Indirect Band Gap Crystals on the Z-Scan Technique
The Photoexcited carrier lifetime (τ) and peak to valley transmission difference (ΔTp-v) in direct and indirect band gap crystals has been investigated by the use of single beam open and closed aperture z-scan technique using frequency doubled Nd:YAG laser. The peak to valley transmission difference (ΔTp-v) is found to be of the order of 10-2 in case of direct band gap crystals and of the order...
متن کاملUltrabroadband few-cycle infrared pulse generation from a noncollinear optical parametric amplifier based on bulk niobate crystals
We describe a near-IR two-stage noncollinear optical parametric amplifier (NOPA) pumped at 800 nm that employs bulk congruent lithium niobate [LiNbO3 (c-LNB)] and bulk potassium niobate [KNbO3 (KNB)] crystals. Noncollinear phase matching in these materials allows for generation of pulses as broad as 2900 cm−1 (∼78 THz) centered in the near-IR at ∼1300 nm. In the particular geometry described he...
متن کاملEffect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...
