Photonic link loss can be minimized by using an RF modulator with lower half-wave voltage (V π), a higher-power laser source, and a higher-power handling detector [52,53]. Realistically, the insertion loss figure can be improved by 28 dB using the waveguide with inverse tapers, a modulator with half the V π , and a high photodetector current of 40 mA.
