New Multi-Axis Alignment System for Silicon Photonics


Auburn, MA – PI’s household of photonics alignment automation techniques has expanded with a brand new air-bearing-based multi-axis meeting and an EtherCat-based high-performance movement controller with embedded alignment algorithms. The distinctive mixture of direct-drive maintenance-free air bearing alignment levels with refined first mild search and alignment routines lead to extraordinary time financial savings – a important consider silicon photonics alignment automation.

​​​​​​How the Alignment System Works

The F-143 alignment system relies on three A-143 air bearing levels in an XYZ configuration. Every axis supplies a journey vary of 25mm, with a most velocity of 250mm/sec, and acceleration as much as 10m/s2. Preloaded air bearings assure distinctive flatness and straightness of 0.25µm and 0.05µm, respectively. The vertical axis stage is provided with an adjustable counterbalance and brake mechanism to offset the pressure of gravity on the motor and forestall potential collisions with a SiPh wafer within the occasion of an influence failure.

A particular, EhterCat-based movement controller with embedded photonics alignment algorithms and user-friendly software program permits the system to carry out alignments as much as 100 occasions sooner than typical optical alignment engines.

Put on-Free and Clear-Room Suitable

The usage of friction-free, wear-free, and maintenance-free parts together with the absence of lubricants makes the air bearing automated alignment system ideally suited to silicon photonics waver probing and different clean-room purposes.

Absolute Encoder Choice

A key characteristic of those levels is the selection of encoders, together with absolute and incremental choices. Absolute encoders present specific place data, facilitating exact willpower of every angular place with out the necessity for incremental counting. This characteristic ensures instant availability of place data upon power-up, enhancing operational effectivity and security.
