1. Arrayed Fiberoptics Corporation Next-generation Fiberoptic Components
OFC 2004 Presentation
Thank you for giving us the opportunity to present our truly revolutionary fiberoptic component technology.
The fiber has the greatest bandwidth of all: theoretically one fiber can carry all the telephone conversations if everyone in the US talks at the same time. In the , extensive fiberoptic networks were built, including Internet backbones. It is the ideal transmission medium for the information age.
At the time only a small portion of fiber bandwidth were used and it was thought to be adequate.
The explosive growth of Internet caused fiber bandwidth exhaustion, and people turn to new fiberoptics technology DWDM for solution.
DWDM is used to transmit 160 channels simultaneously, therefore effectively solving the problem.
Why can’t it solve all the bandwidth problems?
DWDM components are (primitive) hand made and expensive which limits the usage. Many applications such as FTTH can not be realized due to the high cost. We have a solution to reduce cost by 100, thereby enabling its widespread deployment even into homes.
Therefore, we are “the ultimate solution to unlimited bandwidth”.

Manufacturing Cost
We use microfabrication to guarantee the fiber alignment precision.
The actual device is sandwiched between two alignment wafers.
We will get into more detail if you would like to pursue further after this presentation.
Optical “Heart”
~ 15%
Optical “heart” is only ~15% of the total cost of a fiberoptic component
Fiber interface or “packaging” is ~85% of cost
Companies have focused on optical “heart” and traditional packaging
Fiber Interface
~ 85%

All current technology involves individual fiber alignment
Sub-micron alignment is neccessary in many cases
Many expensive piece parts required
Fiberoptic components cost hundreds of dollars each

7. The Breakthrough: VFI – Vertical Fiber Integration
1. Apply LARGE-SCALE semiconductor manufacturing technologies to fiber alignment
align 2 = align 20,000
