InP membrane on silicon (IMOS) technology has shown high potential in realizing high-density photonic circuits with speed and energy benefits. Intrinsic active components offered by the InP membrane promise highest optoelectronic efficiencies. It can also be intimately integrated on electronics wafers with ultrashort interconnect lengths, paving a way towards the convergence of photonics and electronics.

In the non-contact optical measurement techniques, the depth of field limits the range of the measurement. If the step height sample is out of the depth of field, and it will cause the measurement to fail. In this study, the proposed integration framework integrates the movement of PZT (piezoelectric transducer) stage and the algorithm of the multiple-height image fusion. It can precisely define the height discontinuity of the step height sample which is out of the depth of field. In detail, the lead zirconate titanate actuator, namely PZT actuator, moves a fixed distance with 1 μm. And then, the camera captures one sheet of the 2D image. The working distance of PZT is 800 μm. After repeating the cycle of PZT and the camera with 800 times, the 800 sheets of the 2D image are obtained. The algorithm of the multiple-height image fusion enables the 800 sheets of the 2D image to become the one of 3D reconstruction image with the noise. Finally, the filtering algorithm is used to remove the noise in the 3D reconstruction image. In the experiment system with the depth of field 100 μm, the accuracy of the step height sample with 200 μm is about 1 μm (i.e. 0.5%).

We have investigated optical frequency-shift sensitivity of the transmittance channeled spectrum of cascaded-chirped long period fiber gratings (C-CLPGs) to an applied strain from the viewpoint of the sensor use. In the experiment, eight different kinds of C-CLPGs have been fabricated by changing the cascaded distance for two types of CLPGs and the strain-induced spectral shifts are measured by use of a cross-correlation technique which provides highly precise determination of the spectral shift. As a result, it is confirmed that the higher frequency-shift sensitivities of the C-CLPGs to the strain obtain with the higher order of cladding mode.
