Comparison of L1 and L5 Bands GNSS Signals Acquisition

Cyril Botteron, Jérôme Leclère

Nowadays, civil Global Navigation Satellite System (GNSS) signals are available in both L1 and L5 bands. A receiver does not need to acquire independently the signals in both bands coming from a same satellite, since their carrier Doppler and code delay ar ...

Full C and L-Band Transmission at 20 Tbit/s Using Cavity-Soliton Kerr Frequency Combs

Tobias Kippenberg, Victor Brasch, Maxim Karpov, Arne Kordts, Mirjam Pfeiffer

Temporal soliton formation in a Kerr-nonlinear optical micro-resonator leads to a coherent frequency comb covering the C and L-band. We demonstrate WDM transmission with 94 comb lines and an aggregate data rate of 20 Tbit/s. ...
