Microring resonators (MRRs) can be used to generate optical millimetre-wave solitons with a broadband frequency of 40–60 GHz. 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.

Abstract: Microring resonators (MRRs) can be used to generate optical millimetre-wave solitons with a broadband frequency of
40–60 GHz. 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.
