The document discusses the use of microring resonators (MRRs) for generating optical millimeter-wave solitons in the 40-60 GHz range, which can be utilized for data transmission in communication networks. By employing orthogonal frequency division multiplexing (OFDM) techniques, the soliton signals can be multiplexed and modulated, achieving high data rates without inter-carrier interference. The study demonstrates that both single-carrier and multi-carrier optical soliton pulses can be used, facilitating efficient transmission through various OFDM-based systems.

Non-linear light behaviours within MRRs, such as chaotic signals, can be used to generate logic codes (digital codes). The soliton signals can be multiplexed and modulated with the logic codes using an orthogonal frequency division multiplexing (OFDM) technique to transmit the data via a network system. OFDM uses overlapping subcarriers without causing inter-carrier interference. It provides both a high data rate and symbol duration using frequency division multiplexing over multiple subcarriers within one channel. The results show that MRRs support both single-carrier and multi-carrier optical soliton pulses, which can be used in an OFDM based on whether fast Fourier transform or discrete wavelet transform transmission/receiver system. Localised ultra-short soliton pulses within frequencies of 50 and 52 GHz can be seen at the throughput port of the panda system with respect to full-width at half-maximum (FWHM) and free spectrum range of 5 MHz and 2 GHz, respectively. The soliton pulses with FWHMs of 10 MHz could be generated at the drop port. Therefore, transmission of data information can be performed via a communication network using soliton pulse carriers and an OFDM technique. www.ietdl.org IET Commun., pp. 1–10 doi: 10.1049/iet-com.2013.0077 1 & The Institution of Engineering and Technology 2014 E-mail: sevia@fke.utm.my , M.
