“…Not only single optical parametric processes, such as SHG [1][2][3], sum-frequency generation (SFG) [4], and optical parametric oscillation (OPO) [5,6], but also coupled parametric processes, and notably third-harmonic generation [7][8][9], have been achieved in these materials with high efficiency. In recent years, cascaded frequency conversion and electro-optic (EO) coupling (or polarization coupling) have received much research attention [10][11][12][13][14][15][16][17][18][19][20]. We found in these cases only two or three mismatches of wave vector were compensated, which were only special cases included in our united theory [16], however the general case including six mismatches of wave vector is still unsolved.…”

We proposed a method to simultaneously implement birefringence-phase-matching (BPM) and quasi-phase-matching (QPM) second harmonic generation (SHG) and polarization coupling including six mismatches of wave vectors, in general case, in an optical superlattice (OSL). And the numerical simulations of SHG and polarization coupling in the OSL are carried out. The results indicate that unlike those of SHG processes with only one second harmonic (SH) reported, when one e-polarized fundamental pump is injected into the OSL, another o-polarized fundamental wave, an o-polarized and an e-polarized SHs can be simultaneously generated. The magnitudes of the o-polarized fundamental wave and SHs can be manipulated by an external dc electric field, which is useful when frequency conversion and signal tuning are required simultaneously.

“…It is important to investigate the influence of the domain errors of the APLN crystal on the performance of the filter as the errors are uncontrollable in the fabrication process. The method is the same as that in [21]. We keep E y = 0.219 kV mm −1 , T = 298 K, and L = 8 cm unchanged, and then introduce a pair of positive and negative random errors of length, with the same absolute value and within the range of 0-R, for each couple of adjacent crystal blocks with opposite polarization.…”

We propose theoretically a method for designing a narrowband multi-wavelength Šolc-type filter based on the linear electro-optic effect in aperiodically poled lithium niobate. As one of its applications we demonstrate a thermally tuned 100 GHz spaced four-wavelength filter, whose working electric field is only 0.219 kV mm −1 in an 8 cm long crystal. The filter allows four wavelengths to pass simultaneously with a 3 dB bandwidth of 0.26 nm, a passband of 32.5 GHz and a channel isolation of more than 8 dB, which can be tuned by temperature in a wide range at a rate of −0.69 nm • C −1 . It is found that the domain errors of the aperiodically poled lithium niobate crystal within 25% are beneficial to the performance of the filter. The filter will be useful for dense wavelength division multiplexing optical communication systems.
