Inplane Breaks Out Passives

Planar amplifier startup Inplane Photonics Inc. is gearing up to offer some passive components as well.

Inplane designed the components as elements of its erbium-doped waveguide amplifiers (EDWAs) and amplifier arrays, which integrate elements such as variable optical attenuators and pump lasers.

"As we looked at the amplifier, we realized we had really attractive components that could be products in themselves," says Joseph Shmulovich, president and CEO. "It's an interesting fallout from our [EDWA] development."

Shmulovich wouldn't discuss details, as the products are undergoing "last tests and last development stages" before being announced to the world. He did cite monitor arrays as an example of what Inplane might offer.

Inplane is also itching to talk about its waveguide technology, which is good enough to create waveguides on the order of 1 meter long, Shmulovich says. (The waveguide would be a folded-up spiral, not a meter-long line.) But the company won't divulge specifications yet, hoping to present them in a splashy technical paper at some point.

Inplane's latest EDWA array, the four-amplifier GEM-A2000, is being evaluated by prospective customers, Shmulovich says.

Inplane raised $10 million earlier this year, bringing its total funding to $30 million (see Inplane Scores $10M More).
