Special Issue Information

Dear Colleagues,

Micro/nano photoelectric devices significantly impact the development of the advanced optical electronic industry. Significant improvements have been made from the design and manufacturing process of the device to the performance assessment of micro-nano photoelectric devices. These advanced micro/nano-scale photoelectric devices have attracted considerable attention and played a decisive role in various fields such as sensors, optical storage, optical communications, solid-state lighting, imaging system, green energy, material, biomedical applications, etc. The scope of this Special Issue, “Micro/Nano Photoelectric Devices and Applications”, covers various aspects of the design, manufacture, and application of studies on micro-optical or optical sensing devices and their latest development. We welcome you to submit your original document to this Special Issue. Topics of interest include, but are not limited to: 

  • Nanostructured optical/optoelectronic devices;
  • The design and fabrication of micro/nano photoelectronic devices;
  • Micro/nano optical sensors;
  • Advanced technology in optical design, manufacturing, and application for micro/nano photoelectronic devices; 
  • Photoelectronic devices based on thin film coatings;
  • Micro/nano photoelectrical devices and micromachine systems for leading-edge applications;

This study proposes a three-lens design with a short lens length and explores the curved imaging plane and performs a relative illumination analysis. There are two ways to reduce the lens length: shortening the back focal and lens group lengths. We derived the relevant parameter relationships of three lenses using the first-order geometric optics theory. The optical lens length can be controlled within 2 mm. The shorter the lens length, the larger the angle of the chief ray in the image space, resulting in an increase in the field curvature and astigmatism. Third-order Seidel aberrations can be effectively reduced by a curved image plane. We also derived the equations for relative illuminance, solid angle, surface transmittance, and internal transmittance for the short three-lens design. The optical lens design uses a curved image plane to shorten the distance from the off-axis beam image space to the image plane and reduce the incident angle of the chief ray on the image plane. The formula and design results verified by Code V software (version 11.2) show that both the solid angle and relative contrast of the lens can be increased. For the proposed three-lens design with a short lens length, the semi-field angle is 32°, F/# is 2.7, the effective focal length is 1.984 mm, the image plane area is 2.16 mm × 1.22 mm, and the curvature radius of the concave image plane is 3.726 mm. Moroever, the MTF (100 lp/mm) is larger than 52%, the lateral color aberration is less than 2.12 μm, the optical distortion is less than 2.00%, and the relative illumination is greater than 68%.

Advances in imaging of microscopic structures are supported and complemented by adaptive visualization tools. These tools enable researchers to precisely capture and analyze complex three-dimensional structures of different kinds such as crystals, microchannels and electronic or biological material. In this contribution, we focus on 3D cell cultures. The new possibilities can play a particularly important role in biomedical research, especially here in the study of 3D cell cultures such as spheroids in the field of histology. By applying advanced imaging techniques, detailed information about the spatial arrangement and interactions between cells can be obtained. These insights help to gain a better understanding of cellular organization and function and have potential implications for the development of new therapies and drugs. In this context, this study presents a multi-modal light sheet microscope designed for the detection of elastic and inelastic light scattering, particularly Rayleigh scattering as well as the Stokes Raman effect and fluorescence for imaging purposes. By combining multiple modalities and stitching their individual results, three-dimensional objects are created combining complementary information for greater insight into spatial and molecular information. The individual components of the microscope are specifically selected to this end. Both Rayleigh and Stokes Raman scattering are inherent molecule properties and accordingly facilitate marker-free imaging. Consequently, altering influences on the sample by external factors are minimized. Furthermore, this article will give an outlook on possible future applications of the prototype microscope.
