In optical transmission technique using optical polarization, the change of state of polarization (SOP) and the rotation of SOP (RSOP) during optical transmission has a significant impact o the transmission performance. We propose polarized intensity rotational frequency shift keying (PIR-FSK) as a novel modulation technique in change of SOP and RSOP-tolerant optical transmissions. The proposed PIR-FSK signal does not affect the entire intensity of the optical carrier by modulating the sinusoidal signals on each X and Y-polarized optical carrier. Therefore, the proposed PIR-FSK modulation and optical carrier intensity modulation can operate at the same time. Moreover, since the proposed technique does not modulate the signal using the SOP unlike the PolSK, PIR-FSK is not affected by SOP changes that occur during transmission, and the signal does not be degraded even with RSOP. We demonstrated that the signals modulated using the proposed PIR-FSK modulation have higher signal capacity and efficiency compared to the signal modulated using PolSK modulation.

“…The rapid growth of business traffic has caused severe challenges to mobile communication. Due to the increasing shortage of medium and low‐frequency radio spectrum resources and the urgent demand for high‐speed wireless broadband access, people turn their attention to the high‐frequency millimeter‐wave (mm‐wave) band with more abundant spectrum resources, which is ranging from 30 to 300 GHz 1–8 . However, due to the limited bandwidth and other electronic bottlenecks, it would meet a more difficult and challenge to generate mm‐wave signals based on traditional electrical methods 9–12 …”

In this study, we have proposed and verified a new frequency quadrupling scheme to achieve the generation of W band (75 G–110 G) vector millimeter‐wave signal (mm‐wave), in which optical filter is needless. To eliminate constellation overlapping of the generated vector mm‐wave signal caused by phase multiplication in the process of frequency multiplication, precoding assisted technique is adopted. Simulations are done to generate 80 GHz 16 phase‐shift keying (16PSK) modulated vector mm‐wave signals using a 20 GHz radio frequency source and the bit error rate (BER) performance is analyzed in detail. The results show that BER of the generated 10 Gbit/s vector mm‐wave signal is below 3.8 × 10−3, when the input optical power for into photodetector is higher than −5 dBm.

In this paper, we propose a new frequency quadrupling scheme to generate a quadrature phase shift keying (QPSK) modulated vector millimeter-wave signal, in which an optical filter is not necessary. To eliminate constellation overlapping of the generated vector millimeter-wave signal caused by phase multiplication in the process of frequency multiplication, a precoding assisted technique is adopted. The principle and feasibility of the proposed scheme is deduced by a detailed mathematical formula. Simulations are carried out to generate 40 GHz QPSK modulated vector millimeter-wave signals using a 10 GHz radio frequency source and the BER performance is analyzed in detail. The results show that BER of the generated 5/10-Gbaud vector millimeter-wave signal is below 3.8 × 10−3, when the input optical power for into photo-detector is higher than −20.67 dBm.
