LIPAC specializes in optical engine, a key component
for optical interconnect and optical sensors.
Our name, LIPAC, is an abbreviation of “Light Packaging”, which expresses the will and passion to solve the fundamental and technical limitations that photonics industry is suffering from, using the advanced semiconductor package technology.
In the era of the 4th industrial revolution, when the amount of digital data is explosively increasing, LIPAC is constantly challenging to find the way to measure and transmit data in a much accurate and efficient manner.
LIPAC strives to solve these issues by providing total optical solutions based on advanced semiconductor package technology.
Optical Engine for Transceivers
The optical interconnect market is growing rapidly due to the expansion of data centers, the increase in cloud computing, and the global adoption of big data and IoT. Capability of high-speed data transmission is the key to support the market, and LIPAC provides the most innovative and advanced optical packaging solutions to meet the requirements.
The optical engine is a key component for transceivers, which enables the conversion of electrical and optical signal. LIPAC's optical engines complies with IEEE 100GBASE-SR4/CWDM4/LR4, 400G BASE-SR4/DR4/FR4/LR4, and 800G BASE-FR4(DD)/LR4(DD) standards. Also, LIPAC provides the excellent performance for short-reach as well as long-reach applications.
David Park, CEO of LIPAC on assembling any type of photonic and electrical ICs in a single package
David Park, CEO of LIPAC, introduces a new methodology of assembling any type of photonic and electrical ICs in a single package form factor using Advanced Semiconductor Packaging technology such as FOWLP. This new methodology is called Optical System in Package, or O-SiP in short.
What is Optical Engine?
Optical engine refers to a part that implements the most essential functions in a module/product that uses optics. Just as the engine provides power to a car to implement the core function that enables the vehicle to move, the role of the optical engine in the optical module lies in the realization of the core optical function. The configuration of the optical engine includes the optical setup with electronics and control unit.
The function of the optical engine may vary depending on the application. For example, in optical interconnection module, the optical engine is a part that includes a function by converting optical and electrical signals. In the optical sensor module, the optical engine is a part that includes a function to receive the light for image sensing, and when the light source needs to be controlled within the sensor system, the light source and the light source control unit are included. Optical engine groups parts that perform key functions into one unit, and O-SIP is the most suitable technology to integrate various parts for optical engine within a single semiconductor package.
The optical module can be completed by assembling the optical engine and additional blocks as shown in the figure below. In the optical transceiver, the additional block is composed of customized lens and fiber. In the TOF sensor module, which is a kind of optical sensor, the diffuser, lens and its holder are used as an additional block. In particular, the optical engine manufactured with O-SIP provides robust advantages in the assembly because the optical element is completely passivated. If an optical device, vulnerable to external environment and contamination, is used in the form of a conventional chip on board, problems may occur during the assembly process, but the passivated O-SIP has improved ease assembly and robust reliability.
