“…Hessler et al [63] incorporated a COC substrate into an optofluidics device for biosensing. Chen et al [64] exploited COC substrates as waveguides operating from 26 to 40 GHz, and Zhong et al [65] utilized a thin-walled COC tube for a terahertz (THz) waveguide application. These applications are possible because of COCs' high light transmission over a wide range of wavelengths, high refractive index, low birefringence, and large Abbe number.…”

Cyclic olefin copolymers (COC) are amorphous, transparent thermoplastics composed of cyclic olefin monomers (norbornene) and linear olefins (ethene). They are increasingly utilized as fabrication materials for microsystems and microfluidic devices, owing to their promising features of low water absorption, high electrical insulation, long-term stability of surface treatments, and resistance to a broad variety of acids and solvents. Many manufacturing processes for COC-based devices have been developed in recent decades. These methodologies are categorized as replication methods or fast prototyping as common in fabrication of thermoplastic microfluidic devices. This review gives a full discussion of the features of COCs, the various production processes, and the numerous selected applications in microfluidic platforms. The review also explores COC's composition and fundamental features, as well as fabrication processes and applications in a variety of fields, investigates the material's potential advantages and uses, and attempts to create a comprehensive list of COC's possible benefits. Due to their unique features and simplicity of fabrication, COCs are projected to advance the future of microfluidics, microsystems, and optofluidics.

“…Cyclic Olefin Copolymer (COC) was used to design THz waveguiding. The low bulk absorption loss of COC at 1 THz makes it highly popular [18], [19], [20], [21], [22]. The transmission properties of the suggested fiber model were analysed using the full-vector FEM.…”

Photonic Crystal Fiber Technology (PCF) based terahertz (THz) communication is widely considered the key component of future generation high capacity communication and biomedical engineering. The most difficult aspect of employing this technology is minimizing material losses and dispersion over longer distances. In PCF modeling, a wide variety of materials are considered (Zeonex, Silica, Cyclic Olefin Copolymer, etc.). The Cyclic Olefin Copolymer (COC) stands out as a highly flexible material that is both easily fabricable and inexpensive. This study proposed hexagonal porous cladding and core using the Finite Element Method (FEM). A fiber with an optimal core diameter of 300 µm, a low Effective Material Loss (EML) of 0.039456 cm -1 , a low Confinement Loss (CL) of 2.264 × 10 -5 dBcm -1 , dispersion of 0.8594 psTHz -1 cm -1 and V-parameter of 1.42 are obtained for 1 THz operating frequency. The suggested fiber's propagation parameters have been diligently analyzed and obtained promising values. A significant porosity of 65% and power fraction of 29.88% was recorded.

With the rapid development of terahertz (THz) science and technology, THz transmission has attracted widespread attention. Compared with wireless transmission in free space, THz wave can achieve bending, low-loss and stable propagation in the waveguide. Several types of THz waveguides have been reported. Among them, THz hollow waveguide (HWG) possesses the advantages such as simple structure, easy preparation and low cost. Recently, bendable and low-loss plastic THz HWGs has made progress in our group. This paper gives a review of the research progress in the field of the THz HWGs based on plastic tubing materials, including polymer tube waveguide, metal-coated polymer HWG and metal/dielectric polymer HWG. Problems existing in the plastic HWGs and key points of future research work were discussed with consideration of some issues aroused in practical applications.
