Problems solved by technology

[0004] However, full chip integration still has disadvantages: cost of compromised yield, significant optical loss, and reduced manufacturing flexibility of one chip one product
Such large and complex chips have the disadvantages described above

Embodiment Construction

[0083] In general, integrated optical blocks for use in coherent transmitters, receivers and / or transceivers are disclosed herein. As used herein, the term "integrated optical block" includes multiple optical components placed together such that the surfaces of each component abut to form a single integrated monolithic block. The optical components are specifically configured to be placed together such that the surfaces of each component abut to form a single integrated mass. This is different from a discrete optical arrangement, where the optical components are placed separately from each other.

[0084] Typically, multiple optical components may include an optically transmissive block and an interface (eg, dielectric) bonded together in a monolithic block. Such an arrangement allows multiple components to be assembled as a subassembly without affecting the rest of the assembly, and also allows paired surfaces (or interfaces) to be used to improve alignment accuracy between ...

Abstract

Methods and apparatus for use in coherent transmission and reception of optical data signals. An integrated optics block (100) for use in a coherent optical transmitter comprising: a beam splitter (102) configured to split an input light signal into first and second input light signals, to output the first input light signal for use in an optical transmitter chip and to output the second input light signal for use as a local oscillator signal; a polarisation combiner (104) configured to combine first and second received modulated light signals to form an output; and a polarisation rotator (106) configured to rotate the polarisation of the second modulated light signal such that it is substantially orthogonal to the polarisation of the first modulated light signal prior to combining.

Description

technical field [0001] The present disclosure relates generally to optical components. More particularly, the present invention relates to, but need not be limited to, optical components of coherent transmitters, receivers and / or transceivers. Background technique [0002] In this specification, the term "light" will be used in the sense that it is used in optical systems to mean not only visible light, but also electromagnetic radiation having wavelengths outside the range of visible light. [0003] Design criteria for optical components are moving towards smaller size and greater functionality. Typically, this results in a greater degree of integration of components. In particular, the increased functionality of optical chips fabricated from materials such as silicon, silicon dioxide, indium phosphide, and gallium arsenide has made possible the creation of multifunctional and small devices such as optical transmitters and modulators. [0004] However, full chip integrat...
