1 Fabrication for the array type electro-optical modulator (final report)(No.073A40277) We aim in this project to develop a novel array type (12 channels) electro-optic (EO) optical modulator in LiNbO3 with each channel capable of being independently modulated and working at a designated wavelength in the 1550-1565 nm range. Such an array type modulator is seldom studied and not to mention its availability. The PI of this project and his research team have   rich research and development experience in developing novel multi-function photonic devices based on LiNbO3 via accessing the superior integrated optical and nonlinear optical properties of the crystal. Based on these research achievements, the research team has devoted to this project work readily and already accomplished all the set final project goals.In this study, we have successfully designed, fabricated, and characterized a stand-alone and an array type EO Mach–Zehnder interferometers (MZI) in Ti:LiNbO3 and annealed proton-exchanged (APE) waveguides fabricated using the high and relatively low temperature diffusion technologies, respectively. Several commercial grade simulation codes have been used to design and analyze the MZI structures and travelling-wave electrodes and to simulate and help optimize the output performance of the devices. The performance of the   fabricated MZI devices such as waveguide loss, device insertion loss, electrode RF response, and optical RF modulation bandwidth has been characterized to be close to a commercial grade device. The main specifications of the currently developed devices are as follows: working wavelength range: 1530-1570 nm, waveguide propagation loss: ~0.33-1 dB/cm, Y-branch loss: 0.9 dB/each, total insertion loss: <4-6 dB, electrode EO response: 3-dB bandwidth >16 GHz, optical modulation bandwidth: >3 GHz,   DC half-wave voltage: ~5 V, dimension of the bare chip: 40 mm(L)x 1.5 mm(W)x 1 mm(H), dimension of the packaged device: 200 mm (L)x 120 mm (W)x 25 mm (H), etc. All these results meet the final check points set for this project.

14 Fused-quartz Micro-resonator based 100 GHz-spaced Optical Frequency Comb for Optical communication(No.073A40187) Nowadays, optical micro-resonator has been widely applied in many fields, such as sensing, optical frequency comb generation and laser frequency stabilization. Design for the portable coupling and packaging is the most crucial issue to access these applications. In this report, an electromagnet is utilized to   connect between a precession translation stage that used for the laser coupling via taper fiber and the micro-resonator temporally. After packaging, both parts can be separated by switching off the current inside the electromagnet. The laser coupled micro-resonator with portable design is then performed. Optical frequency comb spacing of about 0.8 nm, which corresponded to the DWDM channel spacing of about 100 GHz was successfully generated based on the home-made taper fiber with transmission rate of more than 80 % and high quality factor (Q value) fused quartz micro-resonator.
15 Study Report of   Further Study on the Definition Realization of Metrological Traceability – Cases of Different Types of Measuring Systems(No.073A40183) Metrological traceability requires an established calibration hierarchy in the process of the definition realization of metrological traceability. While the property of a measurement result would not be the same due to the measured device with differentiated calibration hierarchy, we thus find out some discrepancy   appearing for the representation of the main traceable route of metrological traceability diagram when all characteristics required for metrological traceability are to be inspected, and then the traceable property of all the measurement results cannot be interpreted with a specific and fixed format. Hence, this paper will present how to establish and draw metrological traceability diagram step by step to embody the realization of metrological   traceability, and simultaneously satisfy the property of various measurement results with different calibration systems, through which several practical cases are studied with different types of measuring systems in different metrological areas.

17 ISO/IEC Guide 99:2007, International vocabulary of metrology – Basic and general concepts and associated terms (VIM) Traditional chinese translation(No.073A40164) In 1997 the Joint Committee for Guides in Metrology (JCGM), chaired by the Director of the BIPM, was formed by the seven International Organizations that had prepared the original versions of the Guide to the expression of uncertainty in measurement (GUM) and the International vocabulary of basic and general terms in metrology (VIM). The Joint Committee took on this part of the work of the ISO Technical Advisory Group 4(TAG 4), which had developed the GUM and the VIM.
