A hybrid Si photonics integration has been used in developing interferometric fiber optics gyroscope on silicon photonics template. An on-chip Si photonic chip has been used as optical driver of IFOG. With employing wafer bonding technology, efficient optical coupling into Si waveguide has been realized by on-chip integration of SLD. Different SLD optical coupling schemes by hybrid integration will be discussed.

 

This study proposes a novel LGP design with unilateral light emission, which is applied to a curved LED luminaire without reflective sheet. The LGP adopts convex cylindrical features of ϕ1×0.7 (mm), which provides 90% illuminance on the feature side of LGP. A prototype is presented to verify the design.

 

A differential interference contrast microscope (DICM) is proposed . It is the same as a phase-shifting polarizing microscope except one liquid-crystal Savart prisms inserted in between the objective and sample and it possesses an advantage over conventional DICM of without mechanical movements when switching shear directions.

 

A freeform lens construction is proposed to form a specific rotation symmetric beam profile with collimation. The freeform surface is constructed segment-by-segment using a numerical method based on Snell’s law to produce an output beam profile which has both good irradiance user-defined profile and high collimation.

 

In this paper, we describe a design methodology combining ray tracing, FDTD simulation, S-parameter method, and near-to-far-field transformation to establish a standard operation process for designing metalenses system with sub-wavelength structures. The results show a telephoto lens with FOV  20o and thickness less than 6 mm.

 

Volume holographic optical element (VHOE) has been shown its potential to modern IT devices, including near-eye glass. A designer, however, has no an effective approach to design a useful VHOE. The reason is that there are two remain problems which must be solved in the design approach. This talk is aimed to discuss these two problems and the potential solutions will be proposed.

 

This paper build a measurement system, it has both high resolution and fast image recognition. In this system, a 4K line scan camera connects a macro lens with a focal length of 60 mm, and a linear light source is used to measure surface defects of the object.

 

The photorefractive effect is used to manipulate polychromatic spectra. A sinusoidal phase grating is used to diffract polychromatic light. Theoretical analyses and numerical examples show that for different detection angles, the diffracted spectrum exhibits different features, and that specific spectral line selection or line filter effects are achieved.

 

Two-component finite conjugate zoom lenses are widely used in optical systems. Suitable combinations of the component focal lengths are essential for giving successful zoom curves. The solution spaces of the component focal lengths for solving the real and positive thickness from the first to the second components are described.
