The other new diodes, the Ushio HL40063MG and the HL40065MG, are multimode with TE mode
oscillation, blueviolet lasing wavelength of 405nm and very high optical output power of 600mW in a 5.6mm package.
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.
PC composed of dielectric columns in TE mode
of negative refraction phenomenon is more obvious.
For F-P cavity, L =16 [micro]m, it can be deduced that the position of the Nth order TM mode is nearly the same as the (N - 1)th TE mode
. So, Figure 3 only shows TM mode order number variation with wavelength for F-P cavity.
Because the optical power of the randomly polarized light transmitted through the waveguide grating exceeded that of the transmitted TE light, the optical spectrum between the TE mode
and other polarized modes could not be distinguished.
Under the adjusted parameters, the rod-type PhC has photonic bandgap for the TE mode
([E.sub.y], [H.sub.x], [H.sub.z]) covering the frequency range of 0.277 < h[omega]/2[pi]c < 0.410.
The electromagnetic field of a TE mode
, at the angular frequency [omega] = 2[pi]f, can be expressed using the following equations [13, 14]:
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.
That is, the TE mode
can be estimated from the electric field along a strike of the underground structure and the magnetic field at right angles to it.
When electromagnetic wave spread in a nonmagnetic, nonconducting, linear and plane anisotropic medium, the components of electric and magnetic field satisfy the following Maxwell equations for TE mode
Figure 3 shows respectively the spectral response in transmission and reflection for the double bend waveguide and excited by TE mode
through a Huygens surface.
Considering the radiation pattern of the dipole feed, the parallel-plate waveguide between the annular and large reflectors is mainly excited by the lowest order TE mode
. If the reflector (plate) spacing is reduced to less than 0.7 wavelength, the phase velocity of the TE mode
