A new type of buried polymer 1×N multimode interference(MMI)power splitter is presented. Compared with the traditional design of MMI,interference region,input and output waveguides of the MMI power splitter take the shape of reverse taper,then not only the dimension of the splitter and the excess loss is reduced sharply,but also the uniform is en- hanced greatly.
Proposed the conception of effective width based exact modal propagation analysis (MPA)and modified position of input (output) wave-guides and length of multi-mode interference region. Scaned all kinds of structure parameters of 1×4?
This paper advances some strategies and algorithms as to how to test the movementfeasibility and to evade the Mechanic Interference Zone automaticaly for improvingthe automatic control lever and control quality.
The determination of interference zone of tooth shape designed by "envelope path" method, the way of angmentting tooth strength in one-way transmission, and the method of avoiding interference of tooth profile in both direction transmission are described in chain drives.
In this paper, a relational space of articulated variates and the Mechanical Interference Zone (MIZ) between the articulators of Articulated Mechanical System (AMS) are defined. A geometric model for MIZ is shown. To improve the automatization of robotic system control, some strategies and algorithms for verifying the movement feasibility and automatically rounding the MIZ in AMS are presented.
In the wedge-adjusted Talbot interferometer, the writing regions of grating are the near field interferometer region formed directly by the ±1 order diffractive beams through the phase mask, and the far field interferometer region formed by the ±1 order diffractive beams reflected by the two mirrors.
Experimental investigation of three-dimensional supersonic flow of a gas in the interference region of intersecting surfaces
The effect manifests itself in the interference region and is due to stimulated, correlated emission and absorption of photons of both waves.
Finally, we show that the differential cross section in the interference region with correlated emission (absorption) of equal numbers of photons of both waves can be much greater than the corresponding cross section in any other geometry.
Efficient control of the energy exchange between the waveguide modes by means of uniform exposure of their interference region to radiation with another wavelength was observed.
Transient gratings are produced by placing a sample in the interference region of two intersecting intense laser beams.
