O-Band Multimode DFBLD Enables WDM DPS-QKD

Abstract

O-band DPS-QKD using injection-locked multimode DFBLD carrier is proposed with flexible WDM channel selectivity and released constraint on wavelength drift by elevating the freespectral range to flatten the interfered visibility at the 2-Gbit/s bit rate.

Wavelength-Switching in Single-Mode Injection-Locked Dual-Mode DFBLD Enables Phase Shift Keying for QKD

Wavelength selective injection-locking of a 1545.59-/1548.18-nm dual-mode DFBLD with a transient-current-switched single-mode master DFBLD is performed for differential phase-shift-keying and delay-interferometric on-off-keying at 192 MHz that enables secure and complex quantum-key-distribution via alternative wavelength switching.

O-band single-photon quantum key distributor master-to-slave injection-locked DFBLD pair

Cheng-Lin Tsou, Chih‐Hsien Cheng, Atsushi Matsumoto +2 more

In comparison with the rapidly developing progress on the optical C-band (1525-1565 nm) master-to-slave injection-locked transmitter to perform the coherent single-photon quantum key distribution (QKD), the development on the O-band (1250-1350 nm) QKD transmitter is somewhat delayed as the commercially available wavelength-matched narrow-linewidth distributed feedback laser diode (DFBLD) pair is hardly accessible up to now. By using the DFBLDs with only sub-MHz linewidth and relatively deviated wavelength for the first time, this work demonstrates the optically differential-phase-shift-keying (DPS) QKD by an O-band master-to-slave injection-locked DFBLD pair. The master and slave DFBLDs with wavelength fluctuations of ±0.05% and ±0.2 pm are controlled by a thermo-electric cooler with a feedback gain of 100. The 1-bit delay interferometer (DI) under thermo-insulation maintains its visibility at >96% with dP o /P o and dP o /dt measured below ±0.1% and ±1 × 10 −3 mW/s. By RZ-OOK modulating the master DFBLD with step-like power coding at 150 µW to induce π phase shift in the injection-locked slave DFBLD, the rising-/falling-edge DPS envelope distortion of the slave DFBLD diminishes by decreasing the bias current of the master DFBLD from 7I th (35 mA) to 2I th (10 mA). This phenomenon enables the 128-bit DPS-QKD transmission with a quantum bit-error rate (QBER) of 3.57% and a secure key rate of 3.524 kbit/s in the 6-km SMF link. The O-band injection-locked single-photon DPS-QKD bit-stream with a mean photon number of 0.2 #/bit minimizes its decoding QBER to 3.88% and 4.84% for 512-bit and 1024-bit, respectively.
