“…It is well agreed that the dual drive Mach-Zehnder modulators also play a role in light wave communication systems. In this regards, they are suitable as discrete modulators [8,9] as well as monolithically integrated laser modulators [10,11]. The fact is that the applied voltage has nonlinear functions owing to the quantum confined Stark effect.…”

a b s t r a c tIn order to optimize the performance of three level code division multiplexing (3LCDM) at 2×20 Gb/s data rate, signal level spacing technique is investigated in this paper. The 3LCDM performance is improved considerably using both electrical and optical level spacing optimization configurations. The results demonstrate that by optimization, in conditions of the optical signal-to-noise ratio, an improvement of around 4.5 dB can be achieved in both approaches as well as 3.3 dB in the electrical configuration and 3.5 dB in the optical configuration can be accomplished for the 3LCDM in terms of the receiver sensitivity.

“…high-performance optical modulator with a CMOScompatible drive voltage, a large electro-optic (EO) bandwidth, a low optical insertion loss and compatibility with large-scale manufacturing is one of the crucial optical communication devices being pursued. Over the last two decades, significant progress in various material platforms, including the lithium niobate (LN) [1], polymer [2], indium phosphide [3], silicon [4] have been made. Recently, the thin film LN attracts more intention from both research institutions and industry and is considered as a promising photonic integrated circuits (PICs) platform for ultra-highspeed applications.…”

Thin-film lithium niobate on insulator (LNOI) has recently emerged as a promising platform for high-speed optical communication devices. For practical applications, an efficient, polarization-insensitive, misalignment-tolerant and broadband fiber-to-chip optical coupler is necessary. In this paper, we present a fiber-to-chip edge coupler based on trident spot-size convertor (SSC). Experiment shows 1.18/1.10 dB per facet low loss at 1550 nm for TE/TM polarization respectively. A relatively large alignment tolerance (AT) has also been demonstrated. Over a broadband wavelength range from 1490 nm ~ 1640 nm, the edge coupler exhibits a maximum loss of 1.30 dB, a wavelength dependent loss (WDL) of 0.23 dB for TE mode and a polarization dependent loss (PDL) of 0.33 dB when coupled to a single mode fiber (SMF) with a mode field diameter (MFD) of ~6 μm.

“…In particular, the backreflections of conventional MMIs should be avoided in devices consisting of a semiconductor optical amplifier (SOA) and/or a distributed feedback laser diode (DFB-LD). Recently, several groups have reported reflection properties of deep-ridge MMIs using optical low coherence reflectometry (OLCR) [16][17][18][19]. However, there are few reports on quantitative studies of reflection.…”

All-optical wavelength conversion at 10 Gb s −1 is demonstrated in a Mach-Zehnder interferometric wavelength converter (MZI-WC) module with monolithically integrated SOA preamplifiers and tapered-edge multimode interference couplers (TMMIs). A conventional buried-type 1 × 2 MMI coupler exhibits a minimal excess loss of 0.43 dB and a reflectivity of 5.1 × 10 −4 (L MMI = 172 µm, W MMI = 12 µm). We adapt the 1 × 2 TMMI in the MZI-WC to improve back-reflection and poor uniformity, which is a major problem of conventional MMI and Y-branch. A good performance of the MZI-WC monolithically integrated with TMMI and SOA preamplifiers at 10 Gb s −1 is obtained with clear eye patterns, and a power penalty below 1.5 dB at a 10 −9 bit error rate over the whole C band (45 nm span) is obtained. The dynamic input power range is enhanced up to 11.3 dB by adjusting only the injection current of the SOA preamplifier.
