THz frequency generation using MRRs for THz imaging

We propose a new design of THz frequency carrier generation for medical applications. The dense wavelength division multiplexing can be generated by using a Gaussian pulse propagating within a modified PANDA ring resonator and Add/drop filter. Results obtained have shown that region of frequency can be obtained between 30-100 THz. This area of frequency band can be used for medical applications. The broad bandwidth of THz signals can be obtained and available for medical applications, for instance, Terahertz pulsed imaging (TPI). THz imaging for histopathological diagnosis has been successful investigated method, where THz waves are useful for analysis of the histological features, without any painful process. It has been confirmed that the THz radiations have different transmittance through healthy tissues, where the tissues effected by cancer.
