In this article, we will explore the latest advances in fabrication technologies for micro/nano optics and photonics, highlighting their applications, benefits, and future prospects.
Lithography-Based Fabrication
Lithography is a fundamental technique in micro/nano fabrication, involving the transfer of a pattern onto a substrate using light or other forms of radiation. There are several types of lithography, including photolithography, electron beam lithography (EBL), and nanoimprint lithography (NIL). Photolithography is the most widely used technique, employing ultraviolet (UV) light to pattern photoresist materials. EBL and NIL offer higher resolution and are used for the fabrication of nanostructures and devices.
Nanoimprint Lithography
Nanoimprint lithography is a techniques that uses a mold to pattern a substrate, offering high-resolution and high-throughput fabrication. NIL has been used to create nanostructures, such as nanowires, nanodots, and nanoarrays, with feature sizes as small as 10 nm. This technique has been applied in the fabrication of optical devices, including gratings, lenses, and mirrors.
Electron Beam Lithography
Electron beam lithography is a high-resolution technique that uses a focused beam of electrons to pattern a substrate. EBL has been used to create complex nanostructures, including nanowires, nanodots, and nanoarrays, with feature sizes as small as 5 nm. This technique has been applied in the fabrication of optical devices, including waveguides, gratings, and photonic crystals.
Three-Dimensional (3D) Printing
Three-dimensional printing is a rapidly emerging fabrication technique that enables the creation of complex structures with unprecedented precision and accuracy. 3D printing has been used to fabricate micro/nano optical devices, including lenses, mirrors, and beam splitters. This technique offers the potential for rapid prototyping and low-cost fabrication of complex optical systems.
Directed Self-Assembly
Directed self-assembly (DSA) is a technique that uses the self-organization of materials to create complex nanostructures. DSA has been used to create nanostructures, including nanowires, nanodots, and nanoarrays, with feature sizes as small as 10 nm. This technique has been applied in the fabrication of optical devices, including waveguides, gratings, and photonic crystals.
