optical mode

optical mode

[′äp·tə·kəl ‚mōd]
(solid-state physics)
A type of vibration of a crystal lattice whose frequency varies with wave number only over a limited range, and in which neighboring atoms or molecules in different sublattices move in opposition to each other.

With seven or eight control channels, each corresponding to one optical mode (e.g.
Objective: When molecules or molecular materials are placed in the confined field of an optical mode which is resonant with a molecular transition, New hybrid light-matter states can be formed through strong coupling.
In this sense, the asymmetry in the high frequency side of the LO optical mode can be denoted as HFS (high-frequency shoulder) which assumes the combination of the Raman signals located at 344 and 377 [cm.sup.-1], respectively, as proposed in the earlier literature [31, 35, 36].
This is because such a structure allows the optical loss in the waveguide to be minimized, increasing the optical field reflection into the p-cladding layer with the superlattice basing the role of a reflective mirror, so the optical mode distributions are shifted away from the center of the waveguide towards the n-cladding layer [15].
He added, "IPNetSim[TM] comprises of 4 ports, of which 2 ports support 10/100/1000 Mbps in either Electrical or Optical mode, emulating a 1Gbps full duplex pipe.
Comparing this with spectrum of pure FeNi [14], we can see that there is no peak in wave number 2400 [cm.sup.-1] in pure FeNi, because there is no bond between Fe and Ni atoms in this condition and no optical mode excitation is expected.
The narrow MO part of the device generates a stable stationary optical field determined by a single optical mode. The high power emission is achieved during the propagation of this beam along the ideal non-reflective tapered PA part of the device.
These measures have reduced the time to determine the best optical mode by a factor of four, while also doubling accuracy.
Compared with highly nonlinear fiber, the SOI platform has inherent advantages due to the large values of Kerr parameter and Raman gain coefficient, the tight confinement of the optical mode, and the mature and low-cost fabrication process [2].
In addition to optical mode conversion, FiberPlex offers fiber optic products for affordably increasing the capacity of existing fiber optic infrastructure.
In the indirect methods, the frequency of the optical mode is not a part of the eigenvalue of the mathematical formulation, or involve secondary steps to extract the mode frequencies.
It is evident that the acoustic mode depends on the permittivity of semiconductor and dielectric, whereas the optical mode is associated with the permittivity of semiconductor and vacuum.
