“…While the speeds of direct modulation LD are limited up to around 40-50 Gbps presently [3]- [5], it is necessary to raise up this performance 20 fold to achieve "toward over Tbps" transmission speeds. In addition to it, the fundamental potential of light as transmission frequency is much higher.…”

We have proposed and demonstrated a mode selective active-MMI (multimode interferometer) laser diode as a mode selective light source so far. This laser diode features; 1) lasing at a selected space mode, and 2) high modulation bandwidth. Based on these, it is expected to enable high speed interconnection into future personal and mobile devices. In this paper, we explain the mode selection, and the high speed modulation principles. Then, we present our recent results concerning high speed frequency response of the fundamental and first order space modes.

“…Therefore, directly modulated lasers operating at both 50 Gb/s and 56 Gb/s are attracting attention as light sources. There have been some reports on 50-Gb/s operation of directly modulated lasers up to 70°C [5], [6]. We recently demonstrated 56-Gb/s direct modulation at 55°C and 50 Gb/s direct modulation at up to 80°C by utilizing ridge-shaped buried heterostructure (RS-BH) lasers combined with asymmetric corrugation-pitch-modulation (ACPM) grating [7], [8].…”

Direct modulation at 56 and 50 Gb/s of 1.3-µm InGaAlAs ridge-shaped-buried heterostructure (RS-BH) asymmetric corrugation-pitch-modulation (ACPM) distributed feedback lasers is experimentally demonstrated. The fabricated lasers have a low threshold current (5.6 mA at 85°C), high temperature characteristics (71 K), high slope relaxation frequency (3.2 GHz/mA 1/2 at 85°C), and wide bandwidth (22.1 GHz at 85°C). These superior properties enable the lasers to run at 56 Gb/s and 55°C and 50 Gb/s at up to 80°C for backto-back operation with clear eye openings. This is achieved by the combination of a low-leakage RS-BH and an ACPM grating. Moreover, successful transmission of 56-and 50-Gb/s modulated signals over a 10-km standard single-mode fiber is achieved. These results confirm the suitability of this type of laser for use as a cost-effective light source in 400 GbE and OTU5 applications.

In this article we investigate impact of the four wave mixing effect on the quality of the signal in DWDM system, that uses standard G.652 fibre as an optical medium, in the 1310 nm wavelength domain. In particular influence of the fibre parameters like attenuation, chromatic dispersion slope and effective mode area were examined. Moreover, the impact of the input signal extinction ratio was investigated. Simulation were performed as a function of the input power per channel of the modulated signal and channel spacing of the DWDM network.
