The calculations show that the band gap width is about 49.45% (from 0.276 to 0.458) for the TE mode and 5.12% (from 0.385 to 0.406) for the TM mode, respectively.
If the optical probe beam in SOA is decomposed into two mutually perpendicular components, called TE mode and TM mode, then these two components experience different optical properties in the presence of the pump beam.
As an example, when SNR = 12 dB, [P.sub.loss] = [10.sup.-6], Nr = 2, combined with Type - II HARQ, the threshold of TM mode 1 can be calculated according to (16): [[gamma].sub.1] = 0.5827, and at this time we can obtain [mathematical expression not reproducible] =0.7565, [mathematical expression not reproducible] =0.3864, [mathematical expression not reproducible] =0.2541.
From (14) and (27), we can find that the transverse oscillation characteristic frequency [[omega].sub.[beta]] = [square root of [gamma]/2][[omga].sub.i] has important influence on the solution of the ES and TM mode dispersion equation.

The mode order numbers and corresponding wavelengths of TE and TM mode for WGM cavity and F-P cavity can be calculated by (2) and (4) or (3) and (4).
The inset shows the calculated electric field of fundamental TM mode using a 133 nm-thick silicon layer at an angle of 26.1 degrees with water as the overlying medium.
The AlGaInP HL63193MG is a multi-transverse mode laser diode with TM mode oscillation in a 5.6mm diameter tiny TO package.
In the TE mode, this gap appears at the frequency where permeability of DNG material vanishes, called the zero-[mu] gap, but in the TM mode, this gap arises at the frequency where permittivity of DNG material goes to zero, called the zero-e gap.
Since we are interested to study plasmonic behavior we shall restrict our calculation for definite solution only for TM mode. We consider the input magnetic field as
In which the subscripts [k.sub.I.sub.zl] and [k.sub.II.sub.zl]refer to wave numbers for TE and TM mode, respectively.
where [rho], [phi], z are cylindrical coordinates; [gamma], [[gamma].sub.p]--wave propagation coefficients along and across waveguide; [Z.sub.E] is impedance of waveguide for TM mode.
