Description
Technical field
The present invention relates to a kind ofly, specifically be applicable to the sextuple high precision alignment of integrated photonic device such as optical branching device, optical fiber collimator, array waveguide grating etc. and the mechanical hook-up of encapsulation applicable to integrated photon chip and the self-aligning mechanical hook-up of array fibre.
Background technology
Integrated photonic device has compact conformation, volume is little, antijamming capability is strong, consistency of performance is good, reliable and stable, be convenient to outstanding advantages such as automatic batch production, is widely used in optic communication link net and Access Network in recent years Fiber to the home in the technology.The encapsulation of integrated photonic device is to utilize the sub-micrometer precision motion platform that integrated photon chip is aimed at coupling and fixing with array fibre, realizes the high-performance of device.The advanced technology index of estimating at present package quality in the world is that optical loss is lower than 0.15dB, this just requires the mould field distribution between integrated photon chip and array fibre to mate as far as possible, requires the optical axis alignment precision of integrated photon chip optical channel and optical fiber to be controlled at below the 0.1 μ m on the other hand.Therefore a coupling and a bottleneck that is encapsulated into the development of restriction array waveguide device, and packaging cost accounts for 70%～90% of device total cost, the encapsulation time accounts for more than 50% of total production time, thus one stable and fast packaged type will make product have more advantage.
In essence, encapsulation focus on make emission couple light to optical fiber or light to enter the optical power loss that receives waveguide from optical fiber littler.Therefore, aspect the encapsulation and aligning of optical element, mainly be to overcome the insertion loss of the loss of light signal such as optical fiber and reflection loss etc., with the loss that punctual because radial deflection, angular deflection, Waveguide end face is separated, the end face of waveguide core diameter difference and convex surface causes.Can detect and compensate by corresponding fiber-optic signal pick-up unit for inserting loss and reflection loss, also can overcome with corresponding waveguide manufacturing technology and accurate cutting instrument for waveguide core diameter and convex surface of end face, remaining radial deflection, angular deflection and Waveguide end face separates then axial translation that must be by the high-precision aligning mechanical hook-up of 6 DOF and pivot finishes aligning.We can say that sextuple high-precision aligning mechanical hook-up is most important to the raising of the performance of whole optics device package.
