Nonlinear Mach ehnder Interferometer for Enhancement of Contrast and Pulse For the Mach ehnder interferometer (see Figure 1a), the expressions for intensities I1 Compression and I2 at the outputs with the arms (ports) have the kind [10] For the Mach ehnder interferometer (see Figure 1a), the expressions for intensities I1 (t) = 1 – 2(1 – R)R + 2(1 – R)R cos[ + 2(1 – R)B(t)]Io (t). (1) I1 and I2 at the outputs on the arms (ports) possess the type [10] I2 (t) = 2(1 – R)R + 2(1 – R)R cos[ + 2(1 – R)B(t)]Io (t). (2) (1) I (t) = 1 – 2(1 – R)R + 2(1 – R)R cos + two(1 – R)B(t) I (t). Here, I0 is the intensity at the interferometer input (I0 = I1 + I2 ); would be the linear (two) (t) = 2(1 the pulses through cos + 2(1 – R)B(t) I (t). phase differenceIacquired by – R)R + 2(1 – R)Rpropagation along the interferometer arms; B(t) = (2/)Io (t)n2 L could be the nonlinear phase (B-integral) accumulated in both beam splitters; Here, I0 is definitely the intensity at the interferometer input (I0 = I1 + I2); may be the linear L is length with the beam path inside the beam splitters; may be the wavelength; n2 would be the nonlinear phase difference acquired by the pulses during propagation along the interferometer refractive index; and R would be the reflectivity of the beam splitters. arms; B(t) = (2/)Io(t)n2L is the nonlinear phase (B-integral) accumulated in each beam Under the circumstances = and R = 0.5, the value of I1 in Equation (1) may perhaps be precisely splitters; L is length on the beam path within the beam splitters; could be the wavelength; n2 could be the zero in the absence of a nonlinear phase (B = 0). However, at high intensity, the nonlinear refractive index; and R is definitely the reflectivity of your beam splitters. nonlinear phase is accumulated, and the intensity I1 takes on a maximal worth, provided Beneath the conditions = and R = 0.5, the value of I1 in Equation (1) may perhaps be that B = , = and R = 0.5. Consequently, the pulse emerging at this port has a higher exactly zero in the absence of a nonlinear phase (B = 0). Alternatively, at higher intencontrast. Additionally, the pulse duration shortened immediately after reflection in the CM. F.
