綜觀這十年,積體電路依舊遵循著Gordon Moore提出的摩爾定律曲線,每約兩年晶片上元件的密度會變為兩倍,但摩爾本人在論文內有提到這條成長曲線將因物理製程的極限,導致製造不敷成本而在2030年漸漸趨緩,但是全球對於網路傳輸的流量需求卻是每年不斷地以指數增長,如何化解危機提升傳輸量成為亟需解決的課題。
Integrated electronic technology development is still following Moore’s law proposed by Gordon Moore in recent years, which indicates the element density on the chip will be two times every two years. However, Moore said this growth will slow down around 2030 because of physical limitation, but data traffic has a continuing exponential growth. To solve the data explosion problem, silicon integrated photonics devices might be the new direction to this question.
First, photons do not have mass, so they can transmit faster than electrons without heat emission. Second, the mature CMOS fabrication technology can be used to fabricate silicon integrated photonics devices at high volume and low cost. There are several multiplexing technologies to increase data capacity, such as wavelength-division-multiplexing (WDM), mode-division-multiplexing (MDM) etc. We utilize the characteristic of orthogonality between different modes to design a four channel MDM, then we can transmit data carried by different modes without mode disturbance to increase data capacity. In our proposed reduced size four channel MDM, we pick 48 wavelengths in ITU’s DWDM system using OFDM to transmit data, and we reach a total capacity of 11.6Tbit/s for four channels.
We also do some research on triple-mode 3dB power splitter for data transmitted through different modes. This device can be applied in around 40nm window and also can work for three modes. With these research, our group is looking forward to building an efficient transmission system under mode-division-multiplexing technology.
Besides, we also do research in chip to chip transmission for multiple modes. We take other paper’s 2D grating as our reference, and try to figure out how to transmit higher order modes. Finally, we design a 2D grating at a size of 22μm*22μm for center wavelength 1550nm. We use 10G OOK signal to carry data and utilize 1.3m FMF to receive these data to transmit to another chip. The eye diagram and bit error rate results both indicate this element can work well for dual modes in chip to chip transmission.
