“…In order to push the frequency limits of injection-locked laser systems, it is important to understand the physical mechanisms that govern its dynamics. The basic theory has been developed by several groups and can describe a wide array of benefits from the injection-locked laser, including RIN reduction [9]- [15], suppression of nonlinear effects [16]- [18], and relaxation oscillation (RO) frequency enhancement [19]- [23]. Recently, the development of ultrastrong injection locking has greatly enhanced these effects while also introducing special considerations.…”

Abstract-The modulation response of injection-locked lasers has been carefully analyzed, theoretically and experimentally, with a focus on the strong optical injection regime. We derive closed-form solutions to the relaxation oscillation (resonance) frequency and damping term, as well as the low-frequency damping term, and discuss design rules for maximizing resonance frequency and broadband performance. A phasor model is described in order to better explain the enhancement of the resonance frequency. Experimental curves match closely to theory. Record resonance frequency of 72 GHz and broadband results are shown.

“…The group has extensively published on the subject of the optical injection-locking of long wavelength VCSELs, but this pattern of locking a VCSEL with a DFB has remained unchanged since. Several optical injection-locking studies regarding semiconductor lasers have reported frequency-chirp reduction (Lin et al, 1984), (Sung et al, 2004) increased RF link gain , (Chrostowski et al 2007), improved relative intensity noise (Yabre et al, 2000) and diminished non-linear distortion (Chrostowski et al 2007). Although the utilization of a DFB laser to injection-lock a VCSEL is excellent for demonstration of phenomena related to optical injection-locking, its practical application presents two major drawbacks.…”

“…Additionally, a master laser (Agilent N7711A) injects continuous-wave light into the slave laser via a polarization controller (PC) and an optical circulator. The master laser establishes coherence between subsequent pulses and transfers its characteristically low optical linewidth (80 kHz) to the individual modes of the comb [21,23], and reduces the RIN of the comb modes [27]. The comb's center wavelength can be tuned by simultaneously adjusting the emission wavelength of the master laser and the temperature of the DFB slave.…”

Terabit/s super-channels are likely to become the standard for next-generation optical networks and optical interconnects. A particularly promising approach exploits optical frequency combs for super-channel generation. We show that injection locking of a gain-switched laser diode can be used to generate frequency combs that are particularly well suited for terabit/s super-channel transmission. This approach stands out due to its extraordinary stability and flexibility in tuning both center wavelength and line spacing. We perform a series of transmission experiments using different comb line spacings and modulation formats. Using 9 comb lines and 16QAM signaling, an aggregate line rate (net data rate) of 1.296 Tbit/s (1.109 Tbit/s) is achieved for transmission over 150 km of standard single mode fiber (SSMF) using a spectral bandwidth of 166.5 GHz, which corresponds to a (net) spectral efficiency of 7.8 bit/s/Hz (6.7 bit/s/Hz). The line rate (net data rate) can be boosted to 2.112 Tbit/s (1.867 Tbit/s) for transmission over 300 km of SSMF by using a bandwidth of 300 GHz and QPSK modulation on the weaker carriers. For the reported net data rates and spectral efficiencies, we assume a variable overhead of either 7% or 20% for forward-error correction depending on the individual sub-channel quality after fiber transmission.
