We enable high-performance photonic solutions for data communications — from standard passive devices to custom-engineered modules. Components are specified and qualified against applicable Telcordia reliability requirements.

Product Categories

Each category is shown with its engineering summary and representative application areas.

Category	Summary	Application Areas
Coupling MLAs	In a transceiver, coupling efficiency is margin. Our collimating and focusing MLAs are built to coupling budgets — roughness below 5 nm, AR-coated transmission above 99% — for silicon photonics and transceiver platforms where every tenth of a dB counts.	Transceivers · Silicon photonics Edge Coupling
Fiber Arrays	We specify V-groove, 2D, and PM fiber arrays with sub-0.5 µm pitch accuracy and IL below 0.3 dB — qualified to Telcordia for transceiver and coherent applications.	Transceivers · AWG & SiPh Coupling · Coherent
WDM Filters & Modules	We specify thin-film DWDM/CWDM/LWDM filters, including 4Skip0/8Skip0 and GFFs, holding the ITU grid with IL under 0.5 dB from −40 to +85 °C — with Z-BLOCK and micro-optic modules that pack that performance into your transceiver's footprint.	Mux/Demux · 400G/800G · Coherent · EDFA
AWGs	We enable standard, flat-top, and PM AWGs with adjacent-channel isolation above 25 dB — qualified for carrier-grade networks with no moving parts and nothing to align.	DWDM · ROADM · Coherent
Passives & Power Mgmt	We specify and qualify PLC splitters, fused couplers, and VOAs to Telcordia performance standards — sized for access networks and channel power management.	FTTx/PON · Power Balancing · Monitoring
Isolators & Circulators	We specify isolators and circulators with isolation above 40 dB and IL under 0.8 dB — the unglamorous insurance that keeps your transmitters stable for decades.	LD Protection · EDFA · Bi-Di · OTDR

Datacom Photonic Devices · Coupling MLAs

Collimating Arrays

Precision collimation at wafer scale for transceiver and silicon-photonics coupling. Tight pitch and surface control, AR-matched, so coupling margin survives production spread.

Datacom Photonic Devices · Coupling MLAs

Focusing Arrays

Wafer-level focusing arrays that replace discrete lens alignment. Custom radius of curvature matched to your laser and fiber geometry, delivered in production-friendly wafer format.

Datacom Photonic Devices · Coupling MLAs

Custom Coupling MLAs

Your coupling geometry, our wafer platform. Custom pitch, sag, and AR on silicon or fused silica — for CPO assemblies and coupling schemes that catalogs do not cover.

Datacom Photonic Devices · Fiber Arrays

1D V-Groove Fiber Arrays

The proven workhorse of photonic packaging. V-groove arrays hold sub-micron pitch accuracy with low loss and your choice of polish angle — ready for AWG, SiPh, and module assembly.

Datacom Photonic Devices · Fiber Arrays

2D Fiber Arrays

Two-dimensional fiber alignment for co-packaged and multi-channel interconnects. The same sub-micron discipline as 1D arrays, extended into 2D formats for dense photonic packaging.

Datacom Photonic Devices · Fiber Arrays

PM Fiber Arrays

Polarization-maintaining arrays with controlled axis orientation across every channel. Low loss and verified PM alignment for coherent optics, sensing, and QT applications.

Datacom Photonic Devices · WDM Filters & Modules

DWDM Filters (100 / 200 GHz)

Thin-film DWDM filters built on genuine datacom heritage. ITU-grid 100/200 GHz channels with low loss, high isolation, and full −40 to +85 °C qualification for mux/demux, coherent, and GFF.

Datacom Photonic Devices · WDM Filters & Modules

CWDM Filters

Cost-effective coarse wavelength management across 1270–1610 nm. ITU-T G.694.2 compliant with low loss and full temperature range for access and FTTx networks.

Datacom Photonic Devices · WDM Filters & Modules

Z-Block Assemblies

Compact free-space WDM assemblies that squeeze more channels into less module volume. Precise wavelength accuracy in a footprint your transceiver mechanical team will appreciate.

Datacom Photonic Devices · WDM Filters & Modules

Micro-Optic WDM Blocks & Filter Arrays

Custom micro-optic blocks combining filters, collimation, and routing in one aligned unit. Your channel plan, our assembly — for high-density modules and multi-channel sensing.

Datacom Photonic Devices · AWGs

Standard AWG (50 / 100 GHz)

Dozens of wavelengths multiplexed on a single chip. Standard 50/100 GHz AWGs with low loss and high adjacent isolation, qualified for DWDM routing and ROADM line cards.

Datacom Photonic Devices · AWGs

Flat-Top AWG

Wide, flat passbands that tolerate wavelength drift and laser variation. Flat-top response for coherent and high-capacity systems where Gaussian passbands cost margin.

Datacom Photonic Devices · AWGs

PM-AWG

AWG performance with polarization maintained end-to-end. PM fiber interfaces and controlled birefringence for coherent and quantum applications.

Datacom Photonic Devices · Passives & Power Mgmt

PLC Splitters

The FTTx standard, graded honestly by split count. Planar splitters from 1×2 to 1×64 with insertion loss specified per configuration — no flat, misleading numbers.

Datacom Photonic Devices · Passives & Power Mgmt

Fiber Couplers

Simple, stable power splitting and tapping. Fused couplers at 50:50 or 1×N with low loss and high return loss for monitoring and distribution.

Datacom Photonic Devices · Passives & Power Mgmt
