Suresh is the researcher of this paper where the co-authors are the guides. A systematic design procedure has been devised for integrated optic channel waveguides by combining the theory of Titanium indiffusion, theory of dielectric waveguides and coupled mode theory. Various aspects like variation of ordinary and extraordinary refractive indices with diffusion parameters, variation of coupling length with physical fabrication parameters for both TE and TM cases are studied. This will serve as a reference for designers where the effect of fabrication parameters can be foreseen and compensated.

Suresh along with coauthors devised an easy method to measure the mode size of integrated optic channel waveguide. This method uses simple objective, fiber and power meter. The results using this method was compared with standard techniques and agrees so well. This helps researchers to estimate the mode field diameter with no expensive measurement equipment.

Suresh is the researcher in this area and co-authors are the guides. An experimental set up is configured for mode size measurement of channel waveguides at different polarization excitations. The near field at 1310 nm is magnified and projected at a distance and profiling is done using single mode fiber. This simple set up eases the compalex mode size measurements.

An integrated optic directional coupler at 1310 nm is designed and fabricated. In this paper, subsequent pigtailing and packaging techniques developed are described. This includes design and fabrication of silicon V grooves, placement of fibers, polishing at angles, and 12 axis alignment technique. The method described is then followed by many in all packaging of integrated optic devices.

The integrated optic couplers are realized using straight and curved waveguides. During the transition period, these curved waveguides also act as a coupler. In this paper, this is analysed and a method derived to estimate equivalent coupling length due to such transition region. During design, this length has to be reduced from the straight coupler length to achieve better performance.

Computer simulation studies have been conducted on the range side lobe performance of a pulse compression radar system which uses a complementary biphase-coded signal transmission. Such a coding scheme is widely used in mesosphere-stratosphere-troposphere (MST) radars expecting to achieve ideally zero range side lobes to ensure unambiguous detection of signals. However, system parameters, like overall system bandwidth, delay distortion, limiting, amplitude and phase droop within the pulse, can lead to spillover of a target return into adjacent range bins by raising the range side lobe level. The results of the study indicate that a goal of 20-dB range side lobe level can be achieved with matched filter bandwidth and reasonable levels of amplitude and phase distortions in the signal path.
This paper serves as a fundamental paper while designing various subsystems of Indian MST Radar.
