Photonic Crystal Fiber Temperature Sensor using OptiMode

Photonic crystal fibers (PCF) have been extensively investigated for chemical, bio-medical, and environmental sensing applications. PCF provides a unique platform for realizing the desired modal dispersion, birefringence, confinement, and multiplicity characteristics. This can be attributed to the freedom in designing the microstructure geometry. Of significant importance for sensing applications, various chemical, biological, and inorganic materials…

Photonic Crystal Fiber Bio-chemical Sensor using OptiMode

Photonic crystal fibers (PCF) are attractive for chemical, biomedical, and environmental sensing applications.

Create a Chip-to-fiber Butt Coupler

This lesson describes how to create a chip-to-fiber coupler. You will create a model of a simple spot-size transformer based on lateral tapering, as reported in [1]. Highly efficient chip-to-fiber coupling with large alignment tolerances is important for applications of optoelectronic integrated semiconductor devices. Such coupling requires a low-loss change of the light beam spot…
