DOE OPTICS

OMedaSemi can fabricate the following type of DOE,we can do sample level fabrication also the wafer level mass production 

*Beam Shaper DOE(Spiral Phase Plate ,Top Hat )

*Beam Splitting DOE

*Focal Shaping DOE

we have two kind of method to fabricate the DOE 

method 1: EBL/Stepper+etching ---Get the structure of material --For Sample or test 

method 2:Grayscale lithography --Get the strcuture of  photoreisist --For mass production or high power application 

Type1:Multifocal Beam Shaper DOE

Type2:Beam Splitter DOE

2*2Beam Splitter

Cross beam Splitter

1*1Beam Splitter

Circular array Beam Splitter

Ring beam Shapper 

Type:Spiral phase plate

Simulation:                                        Real Test:

Type:Top Hat  beam  Shaper
