Abstract

We have numerically demonstrated an efficient mode multiplexer which can tailor the input field patterns by using a phase controller and a mode coupler formed by four single-mode fibers (SMFs). By connecting the mode multiplexer to a multimode fiber (MMF), two orthogonal higher-order modes of the MMF can be simultaneously excited to form two communication channels. The simulated results show that very low modal interference between the two excited modes can be achieved by using the proposed mode multiplexer. We have also discussed the effect of the distance and size of the SMFs in the mode coupler on the performance of the proposed mode multiplexer.

1. Introduction

Due to the rapidly increased Internet traffic, demand for large transmission capacity has grown dramatically and leaded to research toward polarization-division multiplexing (PDM) [1

]. The MCFs usually contains several hexagonally distributed cores with a larger cladding diameter to avoid coupling of power to the outer polymer coating. Each core functions as an individual transmission channel and thus the transmission capacity can be enlarged several times [6

], different signals independently excite different higher-order modes of MMFs and form independent transmission channels in MMFs. If precise excitation can be carried out, the transmission capacity over MMFs can be several times than that over SMFs [14

], which may degrade the transmission performance over MMFs. To overcome this problem, few-mode fibers (FMFs) with specially-designed index profile are proposed to avoid the excitation of unexpected modes [19

].

In this paper we numerically propose a simple mode multiplexing technique by using a phase controller and a mode coupler formed by four SMFs. Two input signals can be transmitted as two different higher-order modes on a conventional graded-index MMFs without the requirement of specially-designed FMFs. Each mode in the MMF forms a transmission channel and the crosstalk between each channel can be very low due to the orthogonal properties of the guided modes. By varying the core size and core distance of the SMFs in the mode coupler, the properties and performance of the proposed mode multiplexer are discussed.

2. Geometry of the mode coupler

3. Results and discussions

In our simulation, we only discuss the effects of the mode coupler. Thus, the simulation is started with Gaussian-shaped input signals with 180° phase difference at the beginning of the mode coupler. We set the length of the mode coupler to be 1 cm for numerical demonstration. After propagating along the mode coupler, signals are coupled into the MMF. We then measure the power ratio of the first ten guided modes on the MMF to verify the resulted excitation in the MMF. We first consider transmission of signals only from TX1. The SMF core size is fixed at 8.3 μm for the mode coupler formed by the fusing method. As the mode-2-like input signal is transmitted into the MMF, the power ratios of the first ten guided modes are plotted in Fig. 3
Fig. 3 Power ratios for the first ten modes of the MMF for only TX1 transmission. The core size of the SMFs is 8.3 μm and the core distances are (a) D = 10 μm, (b) D = 13 μm, and (c) D = 16 μm.
for variant values of D. As D is 10 μm, the calculated insertion loss is 0.11dB, and one can see that more than 95% power in the MMF is coupled into mode 2. Due to the similar field distribution for mode 9, there is about 1.2% power coupled to mode 9 as shown in Fig. 3(a). The other lost power can be attributed to the coupling to other higher-order modes and mode-field mismatch at the beginning and end of the mode coupler. If we increase the value of D to be 13 μm and 16 μm, the 180°-phase-difference signals becomes more separated, which makes the input filed more unlike the field pattern of mode 2. Thus, other modes are excited and the power coupled to mode 2 is reduced as demonstrated in Figs. 3(b) and 3(c).

We then consider the effect of core size dc on the performance of the mode coupler. Figure 4(a)
Fig. 4 Power ratio versus the core distance D with variant values of dc for (a) mode 2 in MMF with only TX1 transmission and (b) mode 3 in MMF with only TX2 transmission.
shows the power ratio of mode 2 in the MMF versus core distance D for dc is 8.3 μm, 7.0 μm, and 6.0 μm with only TX1 transmission. The smaller values of dc can be accomplished by tapering SMFs to the desired size. For the three values of dc, one can see that the largest power ratio of mode 2 appears as D is around 10~11 μm. As D is larger than 12 μm, the power coupled to mode 2 dramatically decreased for the mismatching of field pattern between the input field and mode 2 field. Thus, as mentioned previously, more unexpected higher-order modes are excited. We have also plotted the calculated power ratio of mode 3 in the MMF with only TX2 transmission in Fig. 4(b). Due to the symmetry of the mode coupler, the same results as in Fig. 4(a) can be obtained.

From the simulation results, it shows that the proposed mode multiplexer can help to realize the excitation of two specified modes in the MMF to form independent communication channels. The proposed mode coupler is an all-fiber device which can realize all-fiber communication systems with compact sizes. The fiber-based mode coupler is a passive device and has no electrical interference. These advantages also make our proposed mode coupler suitable to be applied in other systems, such as WDM-PON. As for the splicing to a MMF, we can use a laser source, power meters, and a polarization maintaining (PM) splicer to achieve rotational fiber core alignment and lateral alignment [6

] to realize low loss splicing for our mode coupler. In addition, by making use of the polarization controllers, 4x4 MIMO processing can also be achieved with our proposed mode multiplexer.
